PHP

this php

 <?php class Books 
{ /* Member variables */ var $price; var $title; 
  /* Member functions */ 
 	function setPrice($par){ $this->price = $par; } 
 	function getPrice(){ echo $this->price ."<br/>"; } 
  	function setTitle($par){ $this->title = $par;} 
 	function getTitle(){ echo $this->title ." <br/>"; } 
} 
?> 

this php

 <?php class Person { public $name; function __construct( $name ) { $this->name = $name; } }; $jack = new Person('Jack'); echo $jack->name; 

php $this

$this - refer properties of a class

Class A {
  	public $myname;
function callme() {
  	$myname = "Function Variable";
    $this->myname = "Member Variable";
    echo $myname; // returns Function Variable
  	echo $this->myname; // return Member Variable
}
  
Hence, I could said the same logic applies to global variable and local variable.
