Restart / redirect
Handy (shortcut) function for reloading, redirecting a page. I used is mainly to prevent the browser asking if the user wants to resend the data, when he is on a posted page.
<?
function restart( $url = false )
{
if( $url == false )
{
$url = explode( '?', $_SERVER['REQUEST_URI'] );
header( 'location: ' . $url[0] );
} else {
header( 'location: ' . $url );
}
// no code needs to be run after calling this function.
die();
}
?>
