It's used in object oriented programming (OOP) with classes. $this refers to the current object.
So $this->setup() in PHPLib is referring to the setup() function within the object. You can get a better explanation and examples by reading the manual page on OOP. http://www.php.net/manual/en/language.oop.php ---John Holmes... ----- Original Message ----- From: "Steve Buehler" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, April 29, 2002 10:37 AM Subject: [PHP] $this-> > I am not an expert at PHP and have been learning it through questions, > books, online help, etc....
