What best practices can be followed to efficiently sort and delete images based on their creation date using PHP?

To efficiently sort and delete images based on their creation date using PHP, you can use the `filemtime()` function to get the creation timestamp of each image file, sort them accordingly, and then delete the unwanted files. 

// Directory containing the images
$directory = 'path/to/images/';

// Get an array of all image files in the directory
$files = glob($directory . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

// Sort the files by creation date
usort($files, function($a, $b) {
    return filemtime($a) - filemtime($b);
});

// Delete files older than a certain date (e.g. 30 days ago)
$deleteBefore = strtotime('-30 days');
foreach ($files as $file) {
    if (filemtime($file) < $deleteBefore) {
        unlink($file);
        echo 'Deleted: ' . $file . PHP_EOL;
    }
}
