PHP Loop through array type stdClass Error

Question

I know this has been asked here: Loop through an array php and I am looking for a very similar solution for ProductName and ProductId but the previous answers are not helping.

Array ( [0] => stdClass Object ( 
[Id] => A048FDBF-67FF-4D28-8F53-7D41DCAC45A9

I am trying this but I am getting the error Cannot use object of type stdClass as array

for ($i = 0; $i < count($events); $i++) {
      echo $events[$i]['ProductId'];
      echo $events[$i]['ProductName'];
}

Is a forloop the best way to do this and do I have to json_decode or some other method to pull the stdClass Object?

Yeah sorry that wasnt clear, print_r ($events) lists the full array. — fr0styc0d3r, Mar 27 '19 at 02:01
It looks like $events is your parent array but that is an array itself so in your case $events[0]->ProductDetail is the array you want to iterate over. — Evo_x, Mar 27 '19 at 02:37

To access items in an array you use the square brackets $array['ProductId']. But to access property in a object you have to use the arrow notation $object->ProductId. You have a mix of both.

You would need to do something like

echo $events[$i]->ProductId;

From the root to access lets say the first product id you would do this

echo $root[0]->ProductDetail[0]->ProductId;

To access all the product ids you would do something like this

$products = $root[0]->ProductDetail;
for ($i = 0; $i < count($products); $i++) { 
    echo $products[$i]->ProductId; 
}

Or

$products = $root[0]->ProductDetail;
foreach($products as $object) {
    echo $object->ProductId;
}

Both produce same results just 2 ways of doing it. There are other ways. I guess these are most common and a way you have tried. I suggest you use whichever you understand best.

If you want to iterate the outer array then you would need a loop for that too. In that case you would have a nested loop.

In my example i assumed you only traversing the inner product details array.

This makes sense I will try this and see how it goes thank you. — fr0styc0d3r, Mar 27 '19 at 02:01

try this and see if it works

foreach($events as $event) {
    foreach($event->ProductDetail as $product) {
        echo $product->ProductId;
        echo $product->ProductName;
    }
}
