What are potential reasons for PHP scripts not functioning as expected when attempting to list files in a directory?

The potential reasons for PHP scripts not functioning as expected when attempting to list files in a directory could include incorrect file paths, insufficient permissions to access the directory, or errors in the PHP code itself. To solve this issue, you should ensure that the file path is correct, check and adjust the directory permissions if needed, and review the PHP code for any errors. 

<?php
$directory = "/path/to/directory";

if (is_dir($directory)) {
    $files = scandir($directory);
    
    foreach ($files as $file) {
        if ($file != "." && $file != "..") {
            echo $file . "<br>";
        }
    }
} else {
    echo "Directory not found.";
}
?>
