What are the best practices for structuring and passing arrays of objects in PHP Soap server and client communication?

When passing arrays of objects in PHP Soap server and client communication, it is best practice to serialize the objects before sending them over the SOAP request. This ensures that the objects are properly formatted and can be easily reconstructed on the client side. Additionally, using associative arrays to store the object properties can help maintain the structure of the objects during transmission.

// Serialize the objects before passing them in the SOAP request
$serializedObjects = [];
foreach ($objectsArray as $object) {
    $serializedObjects[] = serialize($object);
}

// Pass the serialized objects in the SOAP request
$client->someMethod($serializedObjects);
```

On the client side, you can unserialize the objects back into their original form:

```php
// Retrieve the serialized objects from the SOAP response
$serializedObjects = $response->someMethodResult;

// Unserialize the objects back into their original form
$objectsArray = [];
foreach ($serializedObjects as $serializedObject) {
    $objectsArray[] = unserialize($serializedObject);
}
