PHP list of specific files in a directory

Question

The following code will list all the file in a directory

<?php if ($handle = opendir('.')) {     while (false !== ($file = readdir($handle)))     {         if (($file != ".")           && ($file != ".."))         {             $thelist .= '<LI><a href="'.$file.'">'.$file.'</a>';         }     }      closedir($handle); } ?>  <P>List of files:</p> <UL> <P><?=$thelist?></p> </UL> 

While this is very simple code it does the job.

I'm now looking for a way to list ONLY files that have .xml (or .XML) at the end, how do I do that?

Answer 1

You'll be wanting to use glob()

Example:

$files = glob('/path/to/dir/*.xml'); 

Answer 2

if ($handle = opendir('.')) {     while (false !== ($file = readdir($handle)))     {         if ($file != "." && $file != ".." && strtolower(substr($file, strrpos($file, '.') + 1)) == 'xml')         {             $thelist .= '<li><a href="'.$file.'">'.$file.'</a></li>';         }     }     closedir($handle); } 

A simple way to look at the extension using substr and strrpos
