$tempArr = [];
foreach ($data->certificates as $k => $certificate) {
    if (!empty($certificate['testCertificateId'])) {
        $tempArr[$k] = $data->certificates[$k];

hope this fix your issue You need to use the key from your foreach, and unset the variable directly (from the session):
code :
foreach ($_SESSION['cart']  as $key => $arrays3) {
    if($arrays3['id'] == $id){
        unset($_SESSION['cart'][$key]);
    }
}

this will help After you're loop ends, add the following line of code to remove the keys from the offHand array element:
code :
$itemDB['offHand'] = array_values($itemDB['offHand']);

like below fixes the issue I have a little problem with arrays. Here is the code: , You need to unset by key, not by value.
code :
$attributes = array($_SESSION['item_01'] , $_SESSION['item_02'] , $this->item_03 , $this->item_04);
foreach($attributes as $key => $attribute) {
    unset($attributes[$key]);

}
foreach($attributes as $key => $attribute) {
    if(array_key_exists($key, $_SESSION) {
        unset($_SESSION[$key]);
        $this->{$key} = null;// this or next line
        unset($this->{$key};
    }
}
$this->item_01 = null;
$this->item_02 = null;

fixed the issue. Will look into that further I have a foreach loop set up to go through my array, check for a certain link, and if it finds it removes that link from the array.
