as per code
header("location:index.php");
it should work usually but you did not give proper error what you getting .
but following the possible reason :
1.sent header by putting HTML before the header function
2. use of session_start(); before header location
3. use of cookie function like set_cookie also send header again
4. some time simple white space also send a header
<?php
header("location:index.php");
?>
method
so avoid above all header already sent
