What version of PHP is required to use imagefilter()?

The imagefilter() function in PHP requires at least PHP version 5.5.0 to be used. If you are using an older version of PHP, you will need to update your PHP installation to a version that supports imagefilter(). 

// Check if the PHP version supports imagefilter()
if (version_compare(PHP_VERSION, '5.5.0') < 0) {
    die('imagefilter() function requires PHP version 5.5.0 or higher.');
}
