Create Dynamic Images With PHP/MySQL

John Owen — Wed, 05 Aug 2009 22:57:12 +0000

You can view the demo of what we will be creating here: Dynamic Images
I will be using my local server to do this tutorial, first off with need to create some data to use in this tutorial. I have provided a MYSQL Query string for you to use. I am using PHP 5.3 and MySQL 3.2.0.1.

-- Table structure for table `people`
--
 
CREATE TABLE IF NOT EXISTS `people` (
  `id` int(8) NOT NULL AUTO_INCREMENT,
  `first_name` varchar(255) NOT NULL,
  `last_name` varchar(255) NOT NULL,
  `email` varchar(255) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ;
 
--
-- Dumping data for table `people`
--
 
INSERT INTO `people` (`id`, `first_name`, `last_name`, `email`) VALUES
(1, 'Tim', 'Carpenter', 'tim@carpentercentral.com'),
(2, 'Joe', 'Woolen', 'joewoolen@gmail.com'),
(3, 'Harry', 'Melvis', 'hmelvis@live.com'),
(4, 'Jane', 'Suden', 'janes211@yahoo.com'),
(5, 'Sue', 'Baxter', 'suebax@hotmail.co.uk'),
(6, 'Jeremy', 'Yun', 'jerry@jerry123.com');

Summary

You will be retrieving an email from the database then getting the length of the email and inserting it into an image thats size is custom to the length of the text. This prevents email spiders from reading the email.

Step 1 – Connecting To The Database

Create a new file called “config.php” and put this code in it:


define('MYSQL_USER', 'root');
define('MYSQL_PASS', '');
define('MYSQL_DB', 'data_db');
define('MYSQL_HOST', 'localhost');
 
$dbc = @mysql_connect (MYSQL_HOST, MYSQL_USER, MYSQL_PASS) OR die('Could not connect to MySQL: ' . mysql_error() );
 
@mysql_select_db (MYSQL_DB) OR die('Could not select the database: ' . mysql_error() );
?>

Enter your details at MYSQL_USER/PASS/DB, you wont need to change localhost unless you know you need to change it.

Step 2 – Index.php

Create a new file called index.php with this code:






Dynamic Images

This is our template. In the index file we will list the names and then you will be able to click the name and view their email.

Step 3 – Listing The Names

Before we delve into the actual image creation we need to list our names. Insert this PHP code between your two body tags (HERE).


	// Will select all fields except email from table 'poeple'. You can select all fields by using a * (eg. SELECT * FROM people)
	$query = "SELECT id,first_name,last_name FROM people";
	// Run the query & grab the result , if error it will display the error
	$result = mysql_query($query) or die('Mysql error: ' . mysql_error());
	// We now have all data in the result, to retrieve this we need to use the mysql_fetch_array in a while loop
?>
Names

	// the while loop will go though each row and display data from the coloumns
	// the view email link will link to a page called view_email.php with a $_GET function
	while ($row = mysql_fetch_array($result)) { ?>
		 } // in between the two PHP sections the code will go, this makes it easier to read?>

	
    	ID
    	Name
    	
  	

    		 echo $row['id']; ?>
    		 echo $row['first_name'] . ' ' . $row['last_name']; // combines the first & last name to display full name ?>
    		 echo $row['id']; // links the ID to the view_email.php page ?>">View Email

Step 4 – view_webcam.php

Create a new file and name it “view_webcam.php”, enter this code in.

 include('config.php'); ?>




Dynamic Images



	//check if the $_GET variable 'id' isset, if it is run the image creation blabla
	if (isset($_GET['id'])) {
		// include the img.php file to create the email from the var id
		echo ' . $_GET['id'] . '">';
	} else {
		// If no var has been set tell the visitor
		echo 'No ID has been given.';	
	}
?>

Not much but it basically inserts an image with a link to a PHP script, the PHP script acts like a image by chaging the header content type to png.

Step 5- img.php

Create a new PHP file and name it img.php, this is the main part of out tutorial so i’ll explain a lot more


	// Check if the ?id= has been set if so continue
	if (isset($_GET['id'])) {
 
		// connect to the database
		include('config.php');
 
 
		// retrieves info from the row relating to the ID
		function retrieve_info($id) {
		//Build the query to retrieve the email, will retrieve the email by the ID
		$query = "SELECT * FROM people WHERE id='$id'";
		// Run the query and do any error stuff
		$result = mysql_query($query) or die('MySQL Error: ' . mysql_error());
		// Convert the data into an array
		$data = mysql_fetch_array($result);
		// Since this is a function we need to return the data.
		//
		return $data;
	}
 
		// CHANGE THESE VARIABLES
		// Replace path by your own font path
		$font = "sanford.tff";
		// Font size (reccomended do not change) (make divisible by 2 for better results)
		$font_size = 14;
 
 
		//set var
		$data = retrieve_info($_GET['id']);
		$email = $data['email'];
		// Count the amount of characters in the email
		$chars = strlen($email);
		// each character is about 14 pixels so lets width a bit more
		$extra = $font_size - 3;
		// calculate width by multiplying each character by the character width plus extraspace
		$width = ($chars * $extra);
		//height of image
		$height = $font_size + 10;
 
		// Create the acording to the calculated size of the text
		$im = imagecreate($width, $height);
 
		// Create some colors (B&W)
		$white = imagecolorallocate($im, 255, 255, 255);
		$black = imagecolorallocate($im, 0, 0, 0);
 
 
 
		// Add the text
		imagettftext($im, $font_size, 0, 5, ($height - 7), $black, $font, $email);
 
		// Set the content-type
		header('Content-type: image/png');
 
		// Using imagepng() results in clearer text compared with imagejpeg()
		imagepng($im);
		imagedestroy($im);
 
	} else {
		// if there is no $data variable then echo text
		echo 'no data avaliable to create image';
	}
?>

To put it simply this script grabs the users ID name from the GET method using variables in the URL, it then calculates the size of the image by finding out the amounting of characters and multiplying them by the font size. On the white background we grab a font in the current directory to use and write the text of the email around the center of the image. Then it outputs the image, to make the browser read it as a image file we need to change the header. Thats what the header part of the script does.

If no $_GET var for the user ID is found then it will just echo an error.

Conclusion

If you want me to put up a demo just post a comment and i’ll put it up ASAP.
This method can be used to track visitors, give custom user images or an array of other things. Here are the files to download:

Using SimpleXML To Read & Parse XML

John Owen — Fri, 17 Jul 2009 12:49:31 +0000

Before we dive into SimpleXML lets first look at XML. XML (Extensible Markup Language) is a flexible text format for creating structured computer documents. It’s W3C’s recommended standard for creating formats and sharing data on the Web.

An XML document comprises elements, attributes, processing instructions, comments, and entities:

Element: Text delimited by an opening and a closing tag. A tag is a name enclosed within angle brackets.

Attribute: A piece of qualifying information for an element. An attribute consists of a name, an equals sign, and an attribute value delimited by either single-quotes or double-quotes.

Processing instruction: The software that is reading an XML document is referred to as a processor. A processing instruction is additional information embedded in the document to inform the processor and possibly change its behaviour.

Comment: An XML comment begins with the characters: less-than, exclamation mark, minus, minus; and ends with the characters: minus, minus, greater-than. Any text within a comment is intended for a human reader and is ignored by the processor.

Entity: An entity is a compact form that represents other text. Entities are used to specify problematic characters and to include slabs of text defined elsewhere. An entity reference consists of an ampersand, a name, and a semi-colon.

Before we start using simpleXML we have to have an XML file. Heres an example we’ll be using for part of the tutorial.

XML Feed

 version="1.0" encoding="utf-8" ?>
 title="Names">
	>Jim>
	>Bob>
	>Sam>
>

Copy this and create a new XML file from it. I named it names.xml.

Step 1 – Loading The File

We need to load this file into PHP so use this piece of code:

$xml = simplexml_load_file('names.xml');

Step 2 – Basic Reading

An XML feed is made of elements. Each element stores a value. For example:

>Jim>

To start I will show you how to just retrieve the value of one element. I will print the value of name1 to the page.

# You can also use "echo" its the same thing.
# Displays the value of name1 which is "Jim"
print $xml->name1;

If you look at the XML file, you’ll see that the “people” element has an attribute called “title” with the value of “Names”. Use this piece of code to retrieve an attribute.

# You call an attribute just like you would with an array: $array['arrayname/number']
print $xml['title'];

Heres the full code so far, I added an extra line to make the output more easier to understand. You can remove it if you want.

# You can also use "echo" its the same thing.
# Displays the value of  which is "Jim"
$xml = simplexml_load_file('names.xml');
print $xml->name1;
# Seperates outputs (easier to read & understand)
print "
";
# You call an attribute just like you would with an array: $array['arrayname/number']
print $xml['title'];

The output would look like this:

Jim
 
Names

Not much at the moment but this is just the basics. Now onto reading multiple items!

Step 3 – Parsing Multiple Items

Grab this XML data:

 version="1.0" encoding="utf-8" ?>
 title="People">
 
	 id="1">
		>
			>Bob>
			>Turner>
		>
		>42>
	>
 
	 id="2">
		>
			>Andrew>
			>Reed>
		>
		>11>
	>
 
	 id="3">
		>
			>Martin>
			>Surf>
		>
		>21>
	>
 
	 id="4">
		>
			>Joan>
			>Cliffe>
		>
		>37>
	>
 
	 id="5">
		>
			>Sue>
			>Beach>
		>
		>45>
	>
 
	 id="6">
		>
			>Gabriel>
			>Owen>
		>
		>5>
	>
 
	 id="7">
		>
			>Jack>
			>Truscott>
		>
		>17>
	>
 
	 id="8">
		>
			>Jim>
			>Fourgorn>
		>
		>14>
	>
 
	 id="9">
		>
			>Mike>
			>Snider>
		>
		>13>
	>
 
>

I named my XML data “people.xml”. We will now display all three items with a few short lines of code. I will go through the code step by step.

# Load the people.xml file
$xml = simplexml_load_file('people.xml');
# Start a foreach loop. Translation: for every  in the xml file put it into the var $item. 
# now the $item can display all the elements inside the 
foreach($xml->item as $item) {
	# These three print's will display the attribute of the  (ID), display the first and last name joined together
	# and then the age. The 
 and  are for spacing out the results
	print "ID: " . $item['id'] . "
";
	print "Name: " . $item->name->first . " " . $item->name->last . "
";
	print "Age: " . $item->age . "
";
}

In this chunk of code there is actually only 5 proper lines of code to parse a xml file that could have hundreds of entries with the “item” element. The comment’s in the code explain the code step-by-step. Here is the output:

ID: 1
Name: Bob Turner
Age: 42
 
ID: 2
Name: Andrew Reed
Age: 11
 
ID: 3
Name: Martin Surf
Age: 21
 
ID: 4
Name: Joan Cliffe
Age: 37
 
ID: 5
Name: Sue Beach
Age: 45
 
ID: 6
Name: Gabriel Owen
Age: 5
 
ID: 7
Name: Jack Truscott
Age: 17
 
ID: 8
Name: Jim Fourgorn
Age: 14
 
ID: 9
Name: Mike Snider
Age: 13

Step 4 – Filtering

Say we only want to find the item that has the id of 2? Well, this can be achieved easily by adding an IF statement inside the for loop. Heres the updated code:

# Load the people.xml file
$xml = simplexml_load_file('people.xml');
# Start a foreach loop. Translation: for every  in the xml file put it into the var $item. 
# now the $item can display all the elements inside the 
foreach($xml->item as $item) {
	if ($item['id'] == 2) {
		# These three print's will display the attribute of the  (ID), display the first and last name joined together
		# and then the age. The 
 and  are for spacing out the results
		print "ID: " . $item['id'] . "
";
		print "Name: " . $item->name->first . " " . $item->name->last . "
";
		print "Age: " . $item->age . "
";
	}
}

Explanation: If the item’s attribute ID = 1 on the first item then it won’t do anything with that item so it moves onto the next one. It checks the ID to the IF statement again and realizes that the ID = 2, which makes the IF statement’s condition true. This will carry out the code in the IF statement.

If you want to filter but display more than one item then change the condition to this:

($item['id'] == 2 OR $item['id'] == 3)

Lets say we want to only find the people that are between the age of 10 and 21. To do this we will use two IF statements. Since were not comparing an attribute we have to insert a little snippet of code just before the IF statement. Here’s the full code:

# Load the people.xml file
$xml = simplexml_load_file('people.xml');
# Start a foreach loop. Translation: for every  in the xml file put it into the var $item. 
# now the $item can display all the elements inside the 
foreach($xml->item as $item) {
	$age = $item->age;
	if ($age >= 10) {
		if ($age <= 21) {
			# These three print's will display the attribute of the  (ID), display the first and last name joined together
			# and then the age. The 
 and  are for spacing out the results
			print "ID: " . $item['id'] . "
";
			print "Name: " . $item->name->first . " " . $item->name->last . "
";
			print "Age: " . $item->age . "
";
		}
	}
}

The $age var is set to the age in the item element. The first IF statement checks if the age is above or equal to 10, if it is then it will pass onto the next IF statement which will check if the age is below or equal to 21. If it is then it will display the item.

Output:

ID: 2
Name: Andrew Reed
Age: 11
 
ID: 3
Name: Martin Surf
Age: 21
 
ID: 7
Name: Jack Truscott
Age: 17
 
ID: 8
Name: Jim Fourgorn
Age: 14
 
ID: 9
Name: Mike Snider
Age: 13

Step 5 – Reading A Standard RSS Feed

Here is a standard XML RSS Feed:

 version="1.0" encoding="utf-8" ?>
 version="0.91">
>
    >Rarest Animals>
    >http://www.animalinfo.org/rarest.htm>
    >A list of the world's rarest mammals.>
>
 
>
    >The Addax>
    >http://www.animalcorner.co.uk/wildlife/addax.html>
    >The Addax (Addax nasomaculatus), sometimes called the 'screw horn antelope', 
    	because of its twisted horns, is a large, desert dwelling member of the antelope family, 
    	closely related to the Oryx.>
>
>
    >Ethiopian Wolf>
    >http://en.wikipedia.org/wiki/Ethiopian_Wolf>
    >
    The Ethiopian wolf (Canis simensis) is a carnivorous mammal of the family Canidae. 
    It is also known as the Abyssinian wolf, Abyssinian fox, red jackal, red fox, 
    Simien fox, or Simien jackal among other names.>
>
>

Lets take a look at the code to read this and display it.

#Load Feed
$xml = simplexml_load_file('feed.xml');
#Display Feed title and description with a link to the page
print '. $xml->channel->link . '">' . $xml->channel->title . '';
print $xml->channel->description;
print '

';
#Display the items
foreach($xml->item as $item){
	# Display title with link to page
	print '. $item->link . '">' . $item->title . '';
	# display description
	print $item->description;
	# break up the items
	print '
';
}

This will output:

Rarest Animals
A list of the world's rarest mammals.
 
The Addax
The Addax (Addax nasomaculatus), sometimes called the 'screw horn antelope', because of its twisted horns, is a large, desert dwelling member of the antelope family, closely related to the Oryx.
 
Ethiopian Wolf
The Ethiopian wolf (Canis simensis) is a carnivorous mammal of the family Canidae. It is also known as the Abyssinian wolf, Abyssinian fox, red jackal, red fox, Simien fox, or Simien jackal among other names.

Now, this code is basically the same as the first foreach loop with different element names. For every item in the XML file, do this with the elements.

Using Functions Effectivley In PHP

John Owen — Sat, 11 Jul 2009 18:29:16 +0000

Before we start here is a partial definition from wikipedia: A function has an input and an output. The defining property of a function is that, for a given input, there is one and only one output.

Basics

Functions are very simple once you understand them, here is the structure of one:

function () {
 
	}

The PHP code goes inbetween { and }.

Here is an example:

function apple () {
 
		echo 'I have a green apple';
 
	}

As you can see the function name is called apple and when the function is called PHP will output: I have a green apple using echo.

More Complex

Here’s a more complicated example:

function apple () {
 
		// declares the variable apple and sets the text to 'Green Apple'
		$apple = 'Green Apple';
		// returns the variable, which can be used outside the function. Example: $fruit = apple(); echo $fruit;
		return $apple;
 
	}

In this function we declare the variable $apple and set it’s value to ‘Green Apple’, that part is simple but what does the return $apple; bit do? Well, it lets the function have an output. Heres an example to explain better.


   
 
	function apple () {
 
		// declares the variable apple and sets the text to 'Green Apple'
		$apple = 'Green Apple';
		// returns the variable, which can be used outside the function. Example: $fruit = apple(); echo $fruit;
		return $apple;
 
	}
 
	function show_date($show_seconds) {
 
		//if statement, if $show_seconds variable is set to true, the date will also show seconds
		if ($show_seconds == 'TRUE') {
			$date = date("F j, Y, g:i:s a");
		} else {
			$date = date("F j, Y, g:i a");
		}
 
		// return the date either with/without seconds.
		return $date;
}
 
?>

 

//declare the fruit variable and set it's value using the return statement in the function, the output should be 'Green Apple'
$fruit = apple();
// print out the text
echo 'I have a ' . $fruit;
?>

This chunk of code may look a little daunting but dont fear, it just has loads of spaces in it. In the declare functions section, I have exactly the same code as before so don’t worry about that. The next piece of code is how you would execute the function.

$fruit = apple();

I declare the variable $fruit and then call the function apple which returns the variable $apple. The $apple variable’s value is ‘Green Apple’. The $fruit variable now has the value of ‘Green Apple’.

echo 'My piece of fruit is a ' . $fruit;

This chunk of code print’s out ‘My piece of fruit is a Green Apple’. The little . between the text and variable add’s the two strings together.

Completing The Function

Now, it’s time to add parameters to the function.

function show_date($show_seconds) {
 
		//if statement, if $show_seconds variable is set to true, the date will also show seconds
		if ($show_seconds == 'TRUE') {
			$date = date("F j, Y, g:i:s a");
		} else {
			$date = date("F j, Y, g:i a");
		}
 
		// return the date either with/without seconds.
		return $date;
}

I’ll explain it step-by-step.

function show_date($show_seconds)

The function is called ’show_date’, inside the brackets I set a variable for the function called $show_seconds.

if ($show_seconds == 'TRUE') {
			$date = date("F j, Y, g:i:s a");
		} else {
			$date = date("F j, Y, g:i a");
		}

This IF statement will check if the $show_seconds variable is equal to the value of ‘TRUE’. If it is, the $date variable will created and it’s value set to the current date including the seconds. If the $show_seconds variable doesn’t equal ‘TRUE’ then it will set the $date variable to the current date without the seconds.

return $date;

This returns the variable of $date, so the function can be used properly. Here is how the function would be used:

echo show_date('TRUE');

echo show_date('FALSE');

echo show_date();

The first example shows the date including the seconds because the value = TRUE, the second example wouldn’t show the seconds because the $show_seconds variable isn’t equal to TRUE and the third example would be the same as the second. It doesn’t equal TRUE.

You can add as much parameters as you like. Here is an example:

function custom_text($text,$html_tag) {
		// compiles a string into the variable custom, if the text was 'Welcome' and the html_tag was bold then it would look like this: Welcome
		$custom = '<' . $html_tag . '>' . $text . ' . $html_tag . '>';
		// outputs the function
		return $custom;
}

If the $text variable was ‘Welcome’ and the variable $html_tag was ’strong’ then the output would look like:

Welcome

General Practice

It is general practice to hold your functions in a seperate file, this way your scripts don’t get clogged down as much. To use the functions in your PHP script, you can use the include or require function. It only needs to be done once and should look something like this:

 require_once('functions.php'); ?>

To call the functions from this file you would just call the function name as you would normally.

Finish

Here is a redirect function, no explaining needed anymore

function redirect($url) {
		// redirects without user header to another page. 
		echo "";
}
 
 
/* EXAMPLE FOR CALLING REDIRECT FUNCTION
 

//redirects to http://www.google.com
redirect('http://www.google.com');
?>
 
*/

Limiting text by a number of characters/words (strrpos).

Danny — Wed, 01 Jul 2009 20:16:50 +0000

If you need to display source text, but you only want to show an excerpt of it and you will probably use the function strrpos to cut your text by a number of characters. This can look ugly as it cuts the text mid-string. Beneath is a tutorial showing you how to cut your text by a certain amount of characters and at the end of the word.

Below is the full source code with comments for cutting text at the word:

 
$maxchars = 500; //Assign a maximum amount of characters
$content = substr($content, 0, $maxchars); //Cuts of the text by a specified number of characters ($maxchars).
 
$pos = strrpos($content, " "); //Looks for the last space in the text " ") and assigns the position number to $pos.
if ($pos>0) { //Asks if there is a space in the content.
$content = substr($content, 0, $pos); //If so, cut the text at $pos, therefore cutting it at the end of the word.
}
 
echo "$content..."; //Add an additional "..." to the end of your text and print it.

To alter this code to your needs, change “$content” to your source text or assign your source text to that variable. (Eg. $content =”Blah Blah Blah”;). To alter the max number of characters displayed, change “$maxchars” to a different number.

This is a great way to chop your text neatly. Enjoy!

Random Numbers in PHP – Random Dice Roller

Danny — Thu, 28 May 2009 14:25:38 +0000

This tutorial will take a brief look at using random numbers in PHP. I’ve used a dice rolling example to demonstrate how the rand() function can be used to select an image at random. This example can be implemented and used for other applications such as an ad rotation script.

PHP comes with a basic function called “rand()”. It can generate random numbers, depending on what parameters you set. For example:

 
//Print a random number between 5 and 15 (including 5 and 15)
 
echo rand(5, 15);

This will print a random number between 5 and 15, including 5 and 15.

Random Dice Roller

View online demo

This demo illustrates how to use the rand() function to select random images each time the page loads.

Before we get started, here are the dice images I used (Right Click ->Save image as):

Once you have chosen your images, create an array, called “img”:

 
//Create an array for dice images
$img = array();

Next step is to populate your array with mulitple image files:

 
//Populate array with dice images
$img[] = '';
$img[] = '';
$img[] = '';
$img[] = '';
$img[] = '';
$img[] = '';

Note that im storing the HTML for the images in the array.

Now we have our array we need to count the total images stored inside it. Reason being, because we need to generate a random number between 1 & the number of images.

 
//Count images in array (-1 because we don't want to include 0 in the array)
$max = count($img) - 1;

The final step is to generate a random number between 1 & the number of images, select the correct image and print it.

 
//Generate a random number between 1 and 6 - (max)
$count = rand(0,$max);
//Assign $dice with the image chosen in the array
$dice = $img[$count];
 
//Print the dice image
echo $dice;

In my example I have include the option to roll the dice again. This is simply a submit button that refreshes the page. By refreshing your page the images will randomly alternate.

The full souce code is shown below:

 
//Create an array for dice images
$img = array();
 
//Populate array with dice images
$img[] = '';
$img[] = '';
$img[] = '';
$img[] = '';
$img[] = '';
$img[] = '';
 
//Count images in array (-1 because we don't want to include 0 in the array)
$max = count($img) - 1;
//Generate a random number between 1 & 6
$count = rand(0,$max);
//Assign $dice with the image chosen in the array
$dice = $img[$count];
 
//Print the dice image
echo $dice;
