Here is my stock update code
$type = $c['variation'][0]['type'];
$var_store = [];
foreach (json_decode($product['variations'], true) as $var) {
if ($type == $var['type']) {
$var['stock'] -= $c['quantity'];
}
array_push($var_store, $var);
}
Product::where(['id' => $product['id']])->update([
'variations' => json_encode($var_store),
'total_stock' => $product['total_stock'] - $c['quantity'],
]);
