How to quickly judge a large number of remote file header in PHP

Remote file is a jump

Such as

Header ("location:http://www.baidu.com");

Each fetch, may be the same, may be different

Judge about every hour, and you need to judge about 1000 at a time.

I was thinking of using the Get_header function to judge, but found that the efficiency is not high

Do you have any good ways to ask?
