Php image adding Chinese and image watermark code _ PHP Tutorial

Add Chinese and image watermark codes for php images. $ Ico_pic is the watermark image you want to add a watermark to the image. other parameters are described in detail, if you look for this type of code, you can download and save it as a php file. then, the caller $ ico_pic mentioned later is the watermark image you want to add a watermark to the image. other parameters are described in detail, if you look for such code, you can download and save it as a php file, and then use the call method described later to call the watermark image generation code in this document.
