PHP循环数组类型stdClass错误

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 
[ProductDetail] => Array 
    ( 
        [0] => stdClass Object

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?

Answer 1

try this and see if it works

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