[SOLVED] Do I need to exit after header('location')?

[LooieENG]

After I do header('location: somewhere.php') do I need to exit, or will the code after not be read anyway?

i dont think you do, but i had problems using that for some reason. and so i used this instead:

 

           $link_update ="index.php";
          echo "<script language=\"javascript\">";   
          echo "location.href = \"$link_update\"";
          echo "</script>"; 
          exit();

I don't have an actual problem with it, it works, but I was just wondering if I needed to exit after.

[joecooper]

well it stops the script from being parsed by the server. usually the would redirect be at the end of the code anyway. but its a good idea to have it.

Ah, I'll use exit after then, can't do any harm. Thanks.

The reason is because the header will fail if their any ouput before it,

 

think of it this way,

 

if you get an error (thats output) thus the header rediect will fail.. so the exit will stop the code, without the exit, the code would continue.
