How can PHP configuration settings such as memory_limit and upload_max_filesize impact image processing scripts?

PHP configuration settings such as memory_limit and upload_max_filesize can impact image processing scripts by limiting the amount of memory available for processing large images or restricting the size of images that can be uploaded for processing. To solve this issue, you can adjust these configuration settings in your PHP.ini file or in your script using the ini_set() function.

// Increase memory limit
ini_set('memory_limit', '256M');

// Increase upload max filesize
ini_set('upload_max_filesize', '10M');
