Hi, Steve. $this refers to a specific instance of a class. The -> accesses a property or method associated with this class.
So, in your class, say it's class car, and in your constructor you want to initialize the color to red, you'd do $this->color = $red; Outside of the class, with your $car variable, you'd change it by using $car->color = $red; It's similar to the Java "." accessor (and the "this" is also similar to Java's this). I hope this helped! -Natalie -----Original Message----- From: Steve Buehler [mailto:[EMAIL PROTECTED]] Sent: Monday, April 29, 2002 10:38 AM To: [EMAIL PROTECTED] Subject: [PHP] $this-> I am not an expert at PHP and have been learning it through questions, books, online help, etc.... I guess like most people. :) Anyway, I see a lot of scripts that use $this->something and was wondering if this was just another variable or if the "->" has any special meaning. One script from the PHPLIB (menu.inc) has this: $this->setup(); and there are no other times in that .inc file that lists that. The only other thing that comes close is just the "funtion setup()". This is not the only program that I see this in and am just wondering about it and trying to see if it is something that I should be using in my scripts. The only time that I use this is when getting results from a mysql query like this: $result=mysql_query("SELECT $team from games where game_id = '$game_id'"); while (($row = mysql_fetch_object($result))){ $input = $row->$team; Hopefully somebody can explain this to me.
