PHP Header() function not redirecting

I've got a problem with the header function

if ( ! isset($_SESSION['user']) ) {

   header('Location: login.php');

}

There is no echo before the if, the page is empty!

it doesn't redirect me. I've var_dump();'ed something in the If statement and it worked so the if is correct.

The php version is 5.6

You might have outputted something to the browser before header call. First check:

  • is there any html before php opening tag

  • is there any whitespace before php opening tag

  • is another php script included with echo before that script

  • is the coding utf8 with BOM?

Those are possible reasons of your error.

white space may cause the redirect change it to something like

if ( ! isset($_SESSION['user']) ) {

   header('location:login.php');

 }

You can also do following: 

echo "<script>window.location = 'login.php';</script>";

Try this code :-

<?php
if ( ! isset($_SESSION['user']) ) {
?>
<script>
    window.location = 'login.php';
</script>
<?php
}
?>
