PHP session records return only one record

Question

I have multiple record for the session $_SESSION["cart_array"] like

$_SESSION["cart_array"] = array(0 => array("item_id" => sms, "quantity" => $pe, "to" =>$to, "msg" => $message));

please see here https://ideone.com/NZysQc

In my achievement I was trying to output this record in a different page but it output only one record. What is mine doing wrong? This is my tried code:

foreach ($_SESSION["cart_array"] as $each_item) {
    $id = $each_item['item_id'];
    $to = $each_item['to'];
    echo '$to and $id';
}

But it return only one record in the session.

Answer 1

My suggestion would be as such:-

$_SESSION["cart_array"][] = array("item_id" => $sms, "quantity" => $pe, "to" => $to, "msg" => $message);

to form the array and

foreach ($_SESSION["cart_array"] as $each_item) {
    $id = $each_item['item_id'];
    $to = $each_item['to'];
    echo "$to and $id";
}

for the loop, notice the double quotes in the echo .

Answer 2

Change

echo '$to and $id';

For:

echo "$to and $id";

As vars are not parsed inside simple quoted strings.

Your example has only the element 0, so only one element will be shown.

You could array_push your elements to you cart session var to have more than one element. And set it to the new array only if the var is stil not set.

$newItem = array("item_id" => sms, "quantity" => $pe, "to" =>$to, "msg" => $message);
if (empty($_SESSION["cart_array"]))
    $_SESSION["cart_array"] = array(0 => $newItem);
else
    array_push($_SESSION["cart_array"], $newItem);

$_SESSION["cart_array"] = array(0 => array("item_id" => sms, "quantity" => $pe, "to" =>$to, "msg" => $message),1 => array("item_id" => sms, "quantity" => $pe, "to" =>$to, "msg" => $message));

foreach($_SESSION["cart_array"] as $each_item_array) { foreach ($each_item_array as $each_item) { $id = $each_item['item_id']; $to = $each_item['to']; echo "$to and $id </br>"; } }
