This page should help explain header() :- http://uk2.php.net/manual/en/function.header.php Basically, 'headers' are ways of telling the browser what type of content you're about to give it, and what it should do with that content. The could be an instruction not to cache any content, to redirect to another page, to pass the content to another application (i.e. PDF), etc, etc. Rob. -----Original Message----- From: php-objects@xxxxxxxxxxxxxxx [mailto:php-objects@xxxxxxxxxxxxxxx] On Behalf Of Anees Sent: 26 April 2007 09:22 To: php-objects@xxxxxxxxxxxxxxx Subject: use of header() hi friends, can anybody please briefly tell wht are all the use of header() function i just used it only for redirecting the page to some other page ie. header("Location: index.php"); and i noticed its coming in mail function also..
