Get_headers takes too long to get information about a remote file, what should I do?

Question

PHP

At the very beginning of the page loading, I check the existence of the remote file using the Get_headers() function and then form the page content using the received data. There is a problem, accessing some files is too long - I get "504 Gateway Time-out". How to solve this problem? How to limit the time for Get_headers() or something to do so that the "504 Gateway Time-out" error does not occur. Even if Get_headers() doesn't return anything, it doesn't throw an error either.

Answer 1

Increase timeout? Or maybe it's better to find out what the problem is and write the code? Write what you are trying to implement.
