note 92289 added to function.header

It's given in the manual that before the header() nothing should have been output,but Strangely in my (php version 5.2.6) script , I use header() after outputting some HTML but still works fine for me !!! <form method="post" > username = <input name="username" type="text" /> <input type="submit" /> </form> <?php $username = $_POST['username']; if($username == root) { header("Location:adminpage.php"); } ?> This works 100% good for me !!! ---- Server IP: 59.162.86.33 Probable Submitter: 117.198.132.191 ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- https://master.php.net/note/edit/92289 Del: integrated -- https://master.php.net/note/delete/92289/integrated Del: useless -- https://master.php.net/note/delete/92289/useless Del: bad code -- https://master.php.net/note/delete/92289/bad+code Del: spam -- https://master.php.net/note/delete/92289/spam Del: non-english -- https://master.php.net/note/delete/92289/non-english Del: in docs -- https://master.php.net/note/delete/92289/in+docs Del: other reasons-- https://master.php.net/note/delete/92289 Reject -- https://master.php.net/note/reject/92289 Search -- https://master.php.net/manage/user-notes.php
