Will anyone please tell me the redirection code in PHP. That is at particular point, page is redirected to another page.
<?php header('Location: http://www.example.com/'); ?> PHP: Note: You have to send the header BEFORE ANY output is sent to the browser. No white spaces or HTML can be sent, before executing this line.
I never learned PHP and trying to edit an existing code. I am successful in that except page is not redirecting as I want. Please give me exact redirection code.

require_once('../code/tce_page_footer.php'); //============================================================+ // END OF FILE //============================================================+ ?> Above is the code. At red code place, I want this code to redirect.
I think this code will not serve my purpose. It for general page redirection without execution of any code.
Including header('Location: http://www.mysite.com/directory/'); gives following error. ERROR: [2] Cannot modify header information - headers already sent by (output started at /_______.php:52)
USE THIS echo "<meta http-equiv=\"refresh\" content=\"0;url=http://www.mysite.com/directory\">"; IT WILL WORK
But it is header information. Will it not cause page to redirect without execution of code? Also should I include at place of red line on above code?
