OOP-related question

This is done on PHP 3.0.16 Hi folks, I have a problem with these HTTP_ vars. I have a mainpage, call it main. There is an include which carries several settings and other includes like my abstract db-layer class. I include this in my class-function, which works fine for the most variables but $SERVER_ADDR It seems that I cannot get these variable in the function of my class so I have to pass them as argument to the function. I have made an init() function where I pass these vars inside the object But I don´t like to do this, vars like $SERVER_ADDR or *_NAME should be available inside the objects-functions. Is this behaviour normal, or are there any workarounds for it? Hope someone could help. TIA Oliver
