want to check whether there is a way for 
 php to 
 when the user uploads a video, 
 assumes that there is a photo 1000x1000 that exceeds the 200x200 value and height 
, then I force it to 200x200 the other 
 and save it as a file in a certain file may be called small 
, but the original 1000x1000 also needs to be saved, but there is another file called (high)? 
 are there any relevant templates that you can refer to?
