Question

I have a PHP class that looks like this:

class userAuthentication
{
    public static function Authenticate()
    {
        if (isset($_COOKIE['email']))
        {
            verify($someVar, getPass($_COOKIE['email']);
        }
    }

    public static function getPass($email)
    {
    }

    public static function verify()
    {
    }
}

At times (I can’t pin-point exactly when), I get a fatal error :

Call to undefined function getPass()

The error is thrown at the line where I call the function in the above code sample. Why is this happening when the function clearly exists.

Answer 1

It’s a static function in a class. Use self::getPass() or static::getPass() if you want to take advantage of Late Static Binding. Same goes for verify().
