Not Working!

Why doesn't the amount of values in the array get displayed, to reflect what in the array, upon calling the writeShoppingCart() function? - The amount stays at 0, Why is this?

 

<?php
session_start();

function writeShoppingCart()
{
echo count($array);
}

if(isset($_SESSION['ids']) && is_array($_SESSION['ids']))
{
    $array = $_SESSION['ids'];
}
else
{
    $array = array();
}


if (!in_array($_GET['id'], $array))
{
$array[] = $_GET['id'];
}
else
{
  echo "ID Exists";
}
$_SESSION['ids'] = $array;
writeShoppingCart();
print_r($array);
?>

I'm going to assume because you ended the function right after that first echo statement....? Is the error that when you call the function, you get "0" or the fact that the array is not being built?

 

Also, you need to pass the variable $array into the function in order for it to access it..

 

try adding a global:

 

function writeShoppingCart()
{
global $array;
