Are there any best practices or alternative methods to consider when dealing with file listing in PHP?

When dealing with file listing in PHP, it is important to consider best practices such as using the opendir() and readdir() functions to efficiently list files in a directory. Alternatively, you can also use the glob() function to retrieve an array of files matching a specified pattern. 

// Using opendir() and readdir() to list files in a directory
$dir = 'path/to/directory';
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
        }
        closedir($dh);
    }
}

// Using glob() to list files in a directory
$files = glob('path/to/directory/*');
foreach ($files as $file) {
    echo "filename: $file : filetype: " . filetype($file) . "\n";
}
