In this tutorial, we’ll see what is header() function in PHP, its importance, and its uses. So, when HTML webpage renders in the user’s browser then HTTP request’s header first & then the body as a second but it is all received in one HTTP response.

header() function in PHP is used to send raw HTTP header and it must be called before any output is sent to the requester, either by normal HTML tags, blank lines in a file, or from PHP.

The advantages of header function is that we can create and download file on the fly.
