php header location vs php_redirect

Question

What\'s the difference between the function \"HTTP_redirect\" and \"header location\" in PHP ?

When must I use the function \"HTTP_re

Answer 1

1) Header in PHP

header() function sends a raw HTTP header to a client.

The above (taken from the PHP documentation) sends a 404 header back to the client.

2) HTTP Redirect

Redirect to the given url.

 "value"), true, HTTP_REDIRECT_PERM);
