PHP OpenDir - Need to sort results

78 Views Asked by user3138025 At 25 April 2025 at 16:25

I want to display a directory that contains only PDF's. I'd like the user to click on a given line and have the appropriate PDF displayed. I copied some code from this site and had to modify it. I put the "breaking return" tag so that each file would be displayed on a separate line. The following code works fine, but I need the file listings to be sorted alphabetically. I've tried the sort function for $thelist in several places, but I can't seem to get it to work. I appreciate your help.

I changed the code after reading another post here. This works fine:

<?php
$files = glob('hymn_lyrics/*.pdf', GLOB_BRACE);

foreach($files as $file)
    {
        if ($file != "." && $file != "..")
        {
            $thelist .= '<a href="'.$file.'">'.$file.'<br /></a>';
        }
    }
?>
<p>List of files:</p>
<p><?=$thelist?></p>
