global variable in a class

[phprock]

I m worried about global variable inside a class. Although its works but i havn't seen any oop coding in php use global variable inside a class.

is it a good way of oop coding in php ?

$site_name="Testing";


class Testclass{
var $fname="First Name";
function Testclass() {
 global $site_name;
 echo"$site_name";

}

}

absolutely, positively, under no circumstances should you use the global directive inside of a class.

Just make a class property and set it up in your constructor.

Using globals and constants inside of classes takes away the portability that is the main reason to use a class.

thank you for the reply.
what i do in this case. I dont want my user to edit anything in the class file.
they can only chage $them, $path variable.

let say i have a file mainfile.php like this

<?php
include("template.php");

$theme="default";
$path="somelocation";


class Template extends Mytemplate {
 function Template(){
	$this->template_dir = "$path/template/$theme/templates/";
		$this->compile_dir = "$path/template/$theme/templates_c/";
}


}

And every pags i say

<?Php
require_once("mainfile.php");
$tpl= new template();

// and rest of the code goes here

?>

I dont want to pass $theme and $path in the constructor every time i create an object. Because I will have to say

require_once("mainfile.php");
global $theme,$path;
$tpl = new Template($theme,$path);
