How to Access a PHP Class Variable from Outside the Class

The below script demonstrates how to access a PHP class variable from outside the class:

//PHP class starts
//We've put this class within the page but could have put it in a separate file

class myClass {

//variable will be global inside the object
//the variable can be accessed both inside and outside of the class as we will see below

//In PHP5 you declare a variable using public if you want it to be accessible outside the class

public $my_var = 'testing';

function myFunctionName(){
//this function is empty at the moment
//PHP class ends

//create an instance of the class as the $mine object

$mine=new myClass();

//You access a class variable from outside the class using the arrow operator. The arrow tells php that the variable is part of the $mine object

echo $mine->my_var;
