How can the PHP function "filesize()" be utilized to filter out images based on their size in bytes?

To filter out images based on their size in bytes using the PHP function "filesize()", you can first retrieve the file size of each image using this function. Then, you can compare the file size to a specific threshold value to determine if the image meets the size criteria.

$directory = "path/to/images/directory/";
$threshold = 500000; // specify the threshold size in bytes

$images = glob($directory . "*.jpg"); // get all jpg images in the directory

foreach ($images as $image) {
    if (filesize($image) > $threshold) {
        // Image meets the size criteria, do something
        echo $image . " meets the size criteria.\n";
    } else {
        // Image does not meet the size criteria, do something else
        echo $image . " does not meet the size criteria.\n";
    }
}
