Answer / Anurag Chaudhary
The header() function in PHP sends a raw HTTP header to the browser. It can be used to set various HTTP headers like content-type, location, etc. The limitation of the header() function is that it must be called before any actual output is sent (not even a blank line) and can only be called once per page.
