How can one efficiently list files in a directory along with their respective modification dates using PHP?

To efficiently list files in a directory along with their respective modification dates using PHP, you can use the `scandir()` function to get an array of files in the directory, then loop through each file to get its modification date using `filemtime()`. Finally, you can display the file name along with its modification date.

$directory = "/path/to/directory";
$files = scandir($directory);

foreach ($files as $file) {
    if ($file != '.' && $file != '..') {
        $modificationDate = date("Y-m-d H:i:s", filemtime($directory . '/' . $file));
        echo "File: $file | Modification Date: $modificationDate <br>";
    }
}
