This is just a general question, I am not 100% on when to use global $var , and $this->var and how/what about the GLOBAL vars .... Lets say I have one file I call config.php ....here I connect to the db, to ldap etc .... the connection "var" I can then use in a file on its own ... obviously after I include "config.php" .... lets say in config.php my DB connect was $dbconnect .... In my index.php page I then use $dbconnect again .... but do I simply use $dbconnect again ... or must I say global $dbconnect and then use it in the rest of the DB calls? or use GLOBALS .. Within a class I can use $this->var correct ... but its not something to be used in a basic "procedural" if I can call it that page... Lets say with my config.php and its connection to the db ...where I have $dbconnect ...... in a class I can also use it, do I access this var straight as $dbconnect or use $this->dbconnect = $dbconnect (and define it as global $dbconnect first before doing this) I am getting my results and seems to working most of the time, but not sure if I am using calls to global or $this->var ..when its not required and calling the var direct would of sufficed. I have never really used GLOBAL vars, so not sure how this ties in or if it might be even more helpful ... Some suggestions or pointers or examples would be appreciated just to clear up some confusion. Regards Oh and if one class uses methods in another class .... do I instansiate a new object of the other class .... I have seen use of OtherClass::Method .... is this better method of $obj = new OtherClass() use
