How can I safely retrieve this property of this object?

If you're using PHP 7+, you can use the null coalesce operator:

'plan_id' => $subscription->items->data[0]->plan->id ?? $default,

This will evaluate the value if it's available, otherwise it will use the default, without generating any warnings or errors.

Example:

$foo = new stdClass();var_dump($foo->bar->baz->data[0]->plan->id ?? null);

Output:

NULL

You can use an isset function over the entire selector:

isset($subscription->items->data[0]->plan->id) ? $subscription->items->data[0]->plan->id : null;

in PHP version 8

you should use Nullsafe operator as follow:

'plan_id' => $subscription?->items?->data[0]?->plan->id,
