How can I only echo the information in a session that people added by them self? My script:

<?php
session_start();

$array = $_SESSION["wenslijst"];

if (isset($_POST["item"]) && (int)$_POST["item"] > 0)
    {
        if (!isset($_SESSION["wenslijst"]))
        {
            $_SESSION["wenslijst"] = array();
            $_SESSION["aantal"] = array();
        }

        $i = 0 ;
        while ($i < count($_SESSION["wenslijst"]) && $_SESSION["wenslijst"][$i] != $_POST["item"]) $i++;
        if ($i < count($_SESSION["wenslijst"]))
        {
            $_SESSION["aantal"][$i]++;
        }
        else 
        {
            $_SESSION["wenslijst"][] = $_POST["item"];
            $_SESSION["aantal"][] = 1;
        }
}

?>

When I add a product my array looks like this, I only echo the bold message: (see the long code as my spefic number for a product)

Array ( [0] => Array ( [f805862bbd430d0673f3f949249326f3] => ) )

Thanks all for your help.

Aantal means: count

Wenslijst means: wishlist

Do i understand you correctly, that your array looks like this?!

[0] => array(
    "your_super_long_product_key" => array(),
    "another_super_long_product_key" => array(),
    "awesome_super_long_product_key" => array(),
)

So you could access the data like this:

foreach(array_keys($array[0]) as $key) {
    echo $key . "
";
}

This will give you:

your_super_long_product_key
another_super_long_product_key
awesome_super_long_product_key

To loop through your whole array like this use:

foreach($array as $dataset) {
    foreach(array_keys($dataset) as $key) {
        echo $key . "
";
    }
}
