note 54937 added to faq.using

I was tried to use HEADER function to do redirect to other site, but it's doesn't work. it always shown me like this message "Warning: Cannot modify header information - headers already sent by (output started at c:\Apache\htdocs\test.php:1) in c:\Apache\htdocs\test.php on line 2". Event, I used a script code as shown below <?php header("Location: http://www.example.com/"); /* Redirect browser */ /* Make sure that code below does not get executed when we redirect. */ exit; ?> ---- Manual Page -- http://www.php.net/manual/en/faq.using.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54937 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54937&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54937&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54937&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54937&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54937&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54937&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54937&report=yes Search -- http://master.php.net/manage/user-notes.php
