PHP add watermark & ​​proportional thumbnail & fixed height & fixed width class

PHP adds watermark & ​​proportional thumbnails & fixed height & fixed width classes.
When using foreach loop processing, you need to set a sleep time or follow the return value after processing, otherwise the processing will not be completed.
