Tengo el siguiente codigo:
Código PHP:
<?php
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")."GMT");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
?>

Lo tengo para que no guarde en cache la pagina, pero me da este error de headers.
Warning: Cannot modify header information - headers already sent by (output started at D:\Web\index.php:1) in D:\Web\musika3\index.php on line 2
