Fatal error: Cannot redeclare __autoload()

Question

Fatal error: Cannot redeclare __autoload() (previously declared in C:\\xampp\\htdocs\\app\\bootstrap.php:25) in C:\\xampp\\htdocs\\app\\bootstrap.php on line 28

This is the error my bootstrap file throws, and it's a pretty hard error to solve. I did the basic stuff, check if there aren't 2 classes with the same name etc. but that wasn't the case. So the thing is: Whats Next?

This is the __autoload functions I'm using:

function __autoload($class_name)
{
    include_once(BASEURL . DS . 'classes' . DS . 'class.' . strtolower($class_name) . '.php');
}

$db = new Database();
$data = new Data();
$mail = new PHPMailer(true);
$functions = new Functions($db);
$users = new users($db, $data, $mail, $functions);

My Questions:

• How is it possible to solve this error? Especially since there isn't a class which is defined double, and there aren't 2 classes with the same name.

• Is there a way to prevent this error for the next time?

Answer 1

I solved it, thanks to the comments on the OP.

The thing was, I was making use of an iframe to load specific content, which also included the bootstrap.php file. Thats why it shows that's redeclared twice.

Still thanks for all the comments guys.
