Question

Why we do this access control allow origin header php?

Answer 1

Answer:

If you don't have access to configure Apache, you can still send the header from a PHP script. It's a case of adding the following to your PHP scripts: <?php header("Access-Control-Allow-Origin: *"); Note: as with all uses of the PHP header function, this must be before any output has been sent from the server
