mysql - php header location not redirected from 404 -

hi friends have 1 problem redirect page php section.

this php redirect section:

<?php session_start(); if (!(isset($_session['uid']) && $_session['uid'] != '')) { header('location: '.$base_url.'index.php'); exit; } include_once 'includes.php' ; if($_get['user_name']){ $user_name=$_get['user_name']; include_once 'public.php'; } if(empty($_get['user_name'])) { header(location:$url404); }?>

$url404" in includes.php

$url404=$base_url.'404.php';

the problem page not redirect if username empty

you forgot include ", it's not seeing header string.

change header(location:$url404); header("location:" . $url404);

php mysql
