PHP array_push() is pushing object incorrectly into another array before pushing

Question

I'm looping over some data and dynamically creating an object which I want to push into an array.

$messageObj = new stdClass(); $recipientsObj = new stdClass();
$messageObj->message_recipients = Array();

$size = count($results);
for( $j = 0; $j < $size; $j++ ) {
    $recipientsObj->recipient_name = $results[$j]['recipient_name'];
    $recipientsObj->phone_number = $results[$j]['phone_number'];

    var_dump(json_encode($recipientsObj)); // DUMP 1

    array_push($messageObj->message_recipients, clone $recipientsObj);

    var_dump($messageObj->message_recipients); // DUMP 2
}

PROBLEM

// DUMP 1 outputs the expected data - for instance

string(55) "{"recipient_name":"JOHN DOE","phone_number":"123456789"}"

But when I push the object into the array, the object is pushed as an array so I get:

[ [{...}], [{...}], [{...}] ]  // DUMP 2

instead of

[ {...}, {...}, {...} ]

What could be causing this? Am I pushing it the wrong way?

And it may be better to take $recipientsObj = new stdClass(); inside the loop (as local var in the loop scope — dWinder

@Nick you're right - I just tracked down the bug to another section of the code where I'm doing an array_chunk that led to the issue in the question. — Clint_A

Tracked down the bug to a section of the code where I was performing an array_chunk on message_recipients and pushing the chunk to an array ($messageObj->message_recipients) leading to the issue in the question.

So I simply resolved it by equating $messageObj->message_recipients to the chunk instead of array_push() since it is already an array.
