PHP returns 404 status Code, processed by the server

1. Implemented by the header () method,

The simplest way, and there's no limit to the PHP version.

<?php

Header (' http/1.1 404 Not Found ');

Header ("status:404 not Found");

?>

When the server is set to 404 pages, access to the PHP will automatically return 404 status and 404 pages.

2. Using the Http_response_code () method,

If your PHP version is greater than 5.4, you can use this new method

<?php

Http_response_code (404);

?>

Note : If your version is less than 5.4, but you have to use Http_response_code (), here is the code for this method
