Are there best practices for sorting images in PHP based on specific criteria in the file name?

When sorting images in PHP based on specific criteria in the file name, one approach is to use the usort function along with a custom comparison function. This comparison function can extract the relevant criteria from the file names and compare them accordingly to sort the images. 

// Array of image file names
$images = ['image1.jpg', 'image3.jpg', 'image2.jpg'];

// Custom comparison function to sort images based on a specific criteria in the file name
usort($images, function($a, $b) {
    // Extract the criteria from the file names (e.g., numeric value)
    $criteriaA = intval(preg_replace('/\D/', '', $a));
    $criteriaB = intval(preg_replace('/\D/', '', $b));

    // Compare the criteria to sort the images
    if ($criteriaA == $criteriaB) {
        return 0;
    }
    return ($criteriaA < $criteriaB) ? -1 : 1;
});

// Display the sorted images
print_r($images);
