PHP implements remote downloading of files to the local place

Often when writing collector publishing interfaces, I need to use the function of remote attachments, so I wrote a PHP function to remotely download files to the local area. Under normal circumstances, it is enough. If the server supports the CURL function, the program will give priority to CURL. Friends who need it can refer to it.

The code is very simple, so I won’t go into too much nonsense, just give it to you:
