PHP Function: dir_list_images()

This function will make an array of all the images in a directory, it will even include all subdirectories by default.
Again, I built this function for a friend who wanted to batch modify all the images using ImageMagick / GD2.

function dir_list_images($dir,$sub=true) {
    $array = Array();
    if (!is_dir($dir)) return false;
    $od = @opendir($dir);
    while($file = readdir($od)){
        if (substr($file,0,1) == ".") {
        	continue;
        } elseif($sub && is_dir($dir.$file)) {
            array_push($array, dir_list_images($dir.$file."/"));
        } elseif (!is_dir($dir.$file)) && preg_match('/(.jpg|.jpeg|.png|.gif)$/si', $file)) {
            array_push($array, $dir.$file);
        }
    }
    closedir($od);
}

A good example of how this could be used,
this would output an array of all the files:

// Finds all the images from within the current directory
 
// __FILE__ is a global variable that requires PHP 5.0+
 
$files = dir_list_images( dirname( __FILE __ ) .'/' );
 
print_r($files); // Outputs: [0] = "/dir/img.png", [1] = "/dir2/img2.jpg"
 
echo count($files); // (Total number) Output: 2

Would be interested to know if you use this.
If you need a conversion for listing images on windows, let me know.
