Naturally, HTML will parse before PHP. The script is trying to send header information after you’ve already sent output to the browser. HTTP headers are required to be sent before any output from your script, which means that a header function must be placed before any html or even a white space. There are two solutions for this. Either (1) Set the header tags the top of the document, or (2) insert a header redirect by adding this to the very top of the page to force the output buffer:
<?php ob_start();
Then this at the very end of the page (not usually required)
ob_end_flush(); ?>
