how to count all the values in a session

[jasonc]

this is the code that stores the data but how do i count all the values to get a grand total of all.

 

if ($_POST) {
foreach($_POST as $key => $val) {
	if (substr($key, 0, 3) != "add") {
//		echo("key=".$key.". val=".$val.". postval=".$_POST[$key].".<br />");
		// add to sessions variable.
		if ($_POST[$key] > 0) {
						$_SESSION['cart'][$key] = $_POST[$key];
						} else {
								// remove this entry.
								unset($_SESSION['cart'][$key]);
								}
	}
}
}

 

 

i tried this but i always get 0  zero

 

$cartCount = 0;
		  foreach($_SESSION['cart'] as $key => $val) {
		  		$cartCount = $cartCount + $key[$val];
		  }
	  echo($cartCount);

the array as printed out has the number 4 and 14 and i am trying to get the total of all of these values.

 

Array

(

    [cart] => Array

        (

            [3552] => 4

            [3404] => 14

        )

 

)

If, as you say, you want to count the values, then count with the optional parameter COUNT_RECURSIVE.

I think he wants the SUM, so why not just add them together?

He wants array_sum( array $array )
