OOP help using this->

[fantomel]

hello guys i'm having some trouble around here with oop

 

i'm having a function where i have to pass one or two parameters

and i have like this

 

 

$this->_file = str_replace(.....);

on var_dump when i check to see what it outputs from str_replace it says NULL

but if i add before that line

$this->_classname = $_classname; 

works perfectly can someone explain to my why is doing like this? for each parameter that i pass i first need to do $this->_var = $var ?

What's in str_replace(...)? Can you post a more detailed version of your code?
