Question

I have this piece of code

redirect_loc(index.php);

And the definition for this function is somewhere in a functions file.

    function redirect_loc($location=NULL)
{
    if($location!=NULL)
    {
        header("Location:$location");
        exit;
    }
}

When I pass “index.php” (note the quotes around to specify as a string) it works, however passing index.php gives error The requested URL /indexphp was not found on this server.

Why doesn’t this work when it’s not passed as a string ?

Answer 1

The . acts as concatenation operator . Did you see what the name was of the file it couldn’t find? No . … It joined the two “strings” (index and php) together – it thought that’s what you wanted.
