Hi,

I just switched from Procedural Programming to Object Oriented and I was wondering if there was a way to access a function outside of a class?

Example:

function dog($variable) {
 echo $variable . " Bark!";
}

class Cat {
 var $cat = dog("Meow); // this doesn't work ! ! !
/*
* If the function dog were in the class I'd access it by using:
* $this->dog("Meow");
* But Since it's out of the class, I am not sure how to use it.
*/
}

function dog($variable) {
	return $variable . " Bark!";
}

class Cat{
var $cat;
	function Cat(){
		$this->cat = dog("Meow");
		echo $this->cat;
	}
}

A function defined outside of the class can't be used as one of it's method's. Also, just like when defining function variables, when defining var's inside a class, it has to be set to a static value (no constants, functions, or other variables).

You're also missing an end quote after "Meow where you define $cat.

Check php.net for more info, they have OOP sections for both php 4 and 5.
