Explain It plzzzzzz.....

[mldboymail]

function remove_product($pid){
	$pid=intval($pid);
	$max=count($_SESSION['cart']);
	for($i=0;$i<$max;$i++){
		if($pid==$_SESSION['cart'][$i]['productid']){
			unset($_SESSION['cart'][$i]);
			break;
		}
	}
	$_SESSION['cart']=array_values($_SESSION['cart']);

Can Any one explain those lines…i mean why $i & productid enter in session array???

if($pid==$_SESSION[‘cart’][$i][‘productid’]){
unset($_SESSION[‘cart’][$i]);
break;
}
}
$_SESSION[‘cart’]=array_values($_SESSION[‘cart’]);

From the looks of it you have an array in session called Cart…

The cart array consist of 0 to many different carts. Each of those causes can contain 0 to many products.

So the $i seems to be used to identify which cart is in use, So the $i is used to define which cart.

The person who wrote it used session as temporary place to store what the person wanted while they were browsing the site.

That’s my interpretation.
