Can you store multiple arrays in one session? - php

Question

Can you push multiple arrays to one session?
For example
array_push($_SESSION['mySession'], $array);
Problem: When i push another array to my session it removes tha last one in the session.
My case:
Get specific item from database
$meubel = $_GET['meubel'];
$sql = "SELECT * FROM mphp6_meubels WHERE naam LIKE '$meubel' ";
$stm = $pdo->prepare($sql);
$stm->execute();
Make new session if its does not exists:
if(!isset($_SESSION['meubels'])){
$_SESSION['meubels'] = array();
}
Make specific array
while($row = $stm->fetch()){
$meubel = [
'naam' => $row['naam'],
'type' => $row['type'],
'omschrijving' => $row['omschrijving'],
'prijs' => $row['prijs'],
];
}
push it to session
array_push($_SESSION['meubels'], $meubel);
When a button is clicked an ajax reqeust is made:
var url = 'test.php?meubel=' + meubel;
Output the session in a div
document.getElementById("div3").innerHTML = result;
If all ajax code is required please tell me.
Example:
When you buy a seat add it to the session. A seat has property's like: name, description and price. So the session must contain multiple arrays.

You are redefining $meubel each time through the loop so there is only one array. You want to dynamically append each row []:
while($row = $stm->fetch()){
$meubel[] = [
'naam' => $row['naam'],
'type' => $row['type'],
'omschrijving' => $row['omschrijving'],
'prijs' => $row['prijs'],
];
}
Then you probably want to merge instead of push, not sure what end result you want:
$_SESSION['meubels'] = array_merge($_SESSION['meubels'], $meubel);
