PHP novice users often encounter difficulties when attempting to sort directory listings alphabetically. This guide aims to resolve this issue by providing a detailed solution.
The original script, which uses opendir() to display a list of images from a folder, needs to be modified to include a sorting mechanism. The script currently reads each file and manipulates the filename to remove extensions.
To sort the list alphabetically, the following steps are necessary:
The modified script, incorporating these steps, is provided below:
<code class="php"><?php // Read files into array $dirFiles = array(); if ($handle = opendir('Images')) { while (false !== ($file = readdir($handle))) { // Hide folders and files if ($file != "." && $file != ".." && $file != "index.php" && $file != "Thumbnails") { $dirFiles[] = $file; } } closedir($handle); } // Sort files alphabetically sort($dirFiles); // Display sorted list foreach($dirFiles as $file) { // Replace code to modify filename echo "<li><a href=\"Images/$file\" class=\"thickbox\" rel=\"gallery\" title=\"$file\"><img src=\"Images/Thumbnails/$file\" alt=\"$file\" width=\"300\" </a></li>\n"; } ?></code>
With these modifications, the script will now correctly display an alphabetically sorted list of images.
