+Example 1: A singleton (static members)
+=======================================
+
+<?php
+
+	class Counter {
+		var $counter = 0;
+		
+		function increment_and_print()
+		{
+				print ++$this->counter;
+				print "\n";
+		}	
+	}
+	
+	
+	class SingletonCounter {
+		static $m_instance = NULL;
+		
+		function Instance()
+		{
+				if (self::$m_instance == NULL) {
+					self::$m_instance = new Counter();
+				}
+				return self::$m_instance;
+		}	
+	}
+	
+	SingletonCounter::Instance()->increment_and_print();
+	SingletonCounter::Instance()->increment_and_print();
+	SingletonCounter::Instance()->increment_and_print();

+
+Example 2: Factory method (derefencing objects returned from functions)
+=======================================================================
+
+<?php
+	
+	class Circle {
+		function draw()
+		{
+			print "Circle\n";	
+		}
+	}
+	
+	class Square {
+		function draw()
+		{
+			print "Square\n";

+	}
+	
+	function ShapeFactoryMethod($shape)
+	{

+				return new Square();
+		}	
+	}
+	
+	ShapeFactoryMethod("Circle")->draw();
+	ShapeFactoryMethod("Square")->draw();

+
+Example 3: Class constants and class scope
+==========================================
+
+<?php
+
+	class ErrorCodes {
+		const FATAL = "Fatal error\n";
+		const WARNING = "Warning\n";
+		const INFO = "Informational message\n";
+		
+		function print_fatal_error_codes()
+		{
+			print "FATAL = " . FATAL;
+			print "self::FATAL = " . self::FATAL;
+		}
+	}
+	
+	/* Call the static function and move into the ErrorCodes scope */
+	ErrorCodes::print_fatal_error_codes();
+
+?>
+
+Example 4: Regular object method using both local and global functions
+======================================================================
+
+<?php
+
+	class HelloWorld {
+		const HELLO_WORLD = "Hello, World!\n";
+		
+		function get_hello_world()
+		{
+			return HELLO_WORLD;

+	}
+	
+	$obj = new HelloWorld();
+	print "length_of_hello_world() = " . $obj->length_of_hello_world();
+	print "\n";
+?>
+
+Example 5: Multiple derefencing of objects returned from methods
+================================================================
+
+<?php
+
+
+	class Name {
+		function Name($_name)
+		{
+			$this->name = $_name;	
+		}
+		
+		function display()

+=============================
+
+<?
+	class MyException {
+		function MyException($_error) {

+		}
+		
+		function getException()
+		{
+			return $this->error;
