One class, many methods: PHP4.x: Q's

Hi, This might be a real obvious question/answer... but I have been up all night geeking on code, so my mind is kinda mushy -- please be kind. :) I have a class called Randimg. Within that class, I have several methods. Within a few of those methods, I use the below code snippet: $_SERVER['DOCUMENT_ROOT'] What would be the best way to assign the above code to a global variable/constant within the class? Also, within each method, I am returning error strings... I would like to create these as class constants... Or something... What is best way to setup static strings within my class? Basically, I would like to have these strings at the top of my class so potential users can easily change the "settings." ;) Lol, sorry is stoooopid questions... I am still kinda new to PHP OOP. Many TIA's! Cheers, Micky -- Wishlists: <http://snipurl.com/1gqpj> Switch: <http://browsehappy.com/> BCC?: <http://snipurl.com/w6f8> My: <http://del.icio.us/mhulse>
