parsing multidimensional js object in php

I have a js object that looks like this:

0: Object
answer: Object
answer1: "fweq"
answer2: "qwef"
answer3: "fqwef"
answer4: "vrevwe"
question: Object
content: "<p>my content</p>"
title: "test"
type: Object
type: "addmcq"


I am trying to iterate and parse this in php.
However its messing with my head.

My php looks like this:

$question = $_POST['data'];
$question = json_decode($question, true);
var_dump($question);
foreach($question as $q) {
    foreach($q as $item) {
        $type = $item['type'];  //Echoes the type correctly
            echo $item['content']; //Does nothing
            echo $item['answer1']; // Does nothing
            echo $item['answer2']; // --
            echo $item['answer3']; // --
            echo $item['answer4']; // --

    }
}

$type will echo out whatever is in the type object but $item['answer1'] will not.

How can i iterate the answer array?

heres the output of the var_dump(question):

array(1) {
  [0]=>
  array(3) {
    ["question"]=>
    array(2) {
      ["title"]=>
      string(48) "
                    test  
                    "
      ["content"]=>
      string(12) "<p>asetw</p>"
    }
    ["answer"]=>
    array(4) {
      ["answer1"]=>
      string(4) "fweq"
      ["answer2"]=>
      string(4) "qwef"
      ["answer3"]=>
      string(5) "fqwef"
      ["answer4"]=>
      string(6) "vrevwe"
    }
    ["type"]=>
    array(1) {
      ["type"]=>
      string(6) "addmcq"
    }
  }
}
