[php]Random avatar script by Friiks

[php]Random avatar script
Hey!
Some of you may be still thinking about how to create a random avatar - avatar which will show different image when you load it.
Well to be honest it's quite simple, all you need is a web server which allows php and htaccess to be used, some basic php knowledge and avatars you want to be rotating.
Lets start by creating image.php file which will contain our script that will rotate the images.
When you've made the file make a directory named avatars in the same directory image.php is.
When you've done that open image.php and enter this code.
PHP Code
<?php
header("Content-type: image/png"); //tell the script to output a png image
function extension($file){
$extension = explode(".",$file);
$ext = strtolower($extension[count($extension)-1]);
return $ext;
}
//function above strips extension of the file given
function dircontent($directory){
$files = array();
if($dir = @opendir($directory)){
while (($file = readdir($dir)) !== false){
if($file != "." && $file != ".." && extension($file) == 'png'){
$files[] = $file;
}
}
closedir($dir);
}
return $files;
}
//function above gets all files from a directory and picks the ones with extension .png
$images = dircontent("images");//get .png files of directory images
$total = count($images);//get total number of images
$image = "images/".$images[mt_rand(0,$total-1)];//get a random image from the images array
//Decreasing by 1 is needed because arrays start with 0, like
//$images array would be $images[0], $images[1] ... etc. but
//count gets the TOTAL number of values in the array.
$new_image = imagecreatefrompng($image);
//create the image
imagepng($new_image);
//output the image
imagedestroy($new_image);
//destroy the image
?>
So that's the script with explanations.
Next thing to create is the .htaccess file. Do that now and pu it in same directory with image.php!
When you've created it, open it and put this in it
Code
RewriteEngine On
RewriteRule image.png image.php
The above code tells .htaccess to sort of redirect your request to image.php whenever you call image.png.
It isn't actually a redirect, it's a re-write :p
So now you can use the image.
The good things about this script is that you can get a file with an extension .png because many web sites and forums don't allow files which don't have image extension as avatar.
It also reads the directory automatically and gets only the files needed.
The weaknesses are that the script (at the moment) can output only png (gif/jpg... if you set it to) images.
So that's about it.
Dont be afraid to ask me questions about the script.
Hope you find it useful :)
Cheers, Friiks.
