[Warning: Cannot Modify Header Information]

This books is very well thought-out. Love the book.

There's this challenge for me: I, too, can not figure out why this does not work. I'm on hmm. 3 hours ish 4 hours ish? On this.

:'( I tried searching for white space and have not been successful. 

 

function redirect_user ($page = 'loggedin.php') 

{

$url = 'http://' . $_SERVER['localhost'] . dirname($_SERVER['htdocs']);

$url .= '/' . $page;

 

// Redirect the user:

header("Location: $url");

exit(); // Quit the script.

 

}
