HTTP headers are the core part of the HTTP request and response. They carry information about the client browser, the requested page, the server, etc...

for example: php.net/manual/en/function.header.php

 

[allanbroomfield]

The header () function sends a raw HTTP header to a client.
[FONT=&quot]header()[/FONT] is used to send a raw [FONT=&quot]HTTP[/FONT] header.

If your header directive is not working, notice that their should be no space between HTTP header name and the colon ).

Correct:
header("Location:example.com);

incorrect but fail without any notice:
header(Location : example.com);
Since their is no "Location :" HTTP header, it is just left out in the HTTP response.
