$this in constructor

I am confused when $this->name = $name is used, because i cannot understand "name" used for reference, which element it is referring to? Is it the where we declared in start or function args?

everything withing the __construct helps you set the parammetters for your methods in your class. for example

<?php
class test {

public $name;

    function __construct($name) {
         $this->$name = $name
    }

    public function result {
            echo "Hello ". $name;
    }
}

$obj = new test;
// Because i defined the parammetters of my method in my __construct the following will print
// the echo message from my method "result" and set $name to my name.
$obj->result('Ram');
?>

In $this->name = $name , the first "name" is a property of the class, and the second "$name" is the variable value that you are assigning to it. $name could have been passed into the function, or declared within the class.
