How can you sort files based on creation or modification date in PHP?

To sort files based on creation or modification date in PHP, you can use the `filectime()` function to get the creation time of a file, `filemtime()` function to get the modification time of a file, and `usort()` function to sort the files based on these timestamps. 

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

usort($files, function($a, $b) use ($directory) {
    $fileA = $directory . '/' . $a;
    $fileB = $directory . '/' . $b;
    
    return filemtime($fileA) - filemtime($fileB);
});

foreach ($files as $file) {
    echo $file . "\n";
}
