What are common challenges faced by PHP beginners when sorting images based on specific criteria?

One common challenge faced by PHP beginners when sorting images based on specific criteria is understanding how to extract and compare the criteria from the image metadata. To solve this issue, beginners can use PHP libraries like ExifTool or PHP's built-in functions to extract metadata such as image dimensions, file size, creation date, etc., and then sort the images based on these criteria. 

// Example code to sort images based on creation date

$images = glob('path/to/images/*.jpg');

usort($images, function($a, $b) {
    $aCreationDate = filectime($a);
    $bCreationDate = filectime($b);

    if ($aCreationDate == $bCreationDate) {
        return 0;
    }

    return ($aCreationDate < $bCreationDate) ? -1 : 1;
});

foreach ($images as $image) {
    echo $image . "\n";
}
