PHP Dir Sorting

[OffCourse]

Hi

I have the following piece of code, which is then used by a flash application to display the pictures in a directory and make a slideshow.

How can I sort the files in the directory based on, let's say, filename?

PHP Code:

<images>
<?php
$dir = "slideshow/";

if (is_dir($dir)) {

    if ($dh = opendir($dir)) {
    
        while (($file = readdir($dh)) !== false) {

            $filetype = substr($file,-3);
            $filetype = strtolower($filetype);
                        
            if ($filetype == "jpg" || $filetype == "gif") { ?>
    <pic>
        <image>slideshow/<?php echo $file;?></image>
        <caption><?php echo $file;?></caption>
    </pic>
<?php            
            }
        }
        closedir($dh);
    }
}
?>
</images>

Thanks for the help.

Instead of looping through and displaying the files, loop through and add each file an array(), and then simply use the sort() function.

Once the array is sorted, just loop through the array and display the results.

If the process seems unclear I can post an example.
