PHP which is the best practise of header location

Question

I have a confusion in using PHP header location. which way is best practice...?

if(true){
    header("location:somepage.php");
}

or

if(true){
    header("location:somepage.php");
    exit;
}  

Answer 1

After sending the `Location:' header PHP will continue parsing, and all code below the header() call will still be executed. So instead use your second example:

if(true){
       header("location:somepage.php");
       exit;
  }
