Unable to access object properties from URL params in Laravel - php

Question

I am trying to access object properties from a request from my Angular app. I am using Laravel 5.1
Angular:
console.log('getQuestionAnswers', params);
return $http({
method: 'GET',
url: url + ver + '/questions/checkMany',
params: {
'questions[]' : params
},
headers: {
'Content-Type': 'application/json',
Authorization: 'Bearer ' + $rootScope.access_token
},
cache: true
});
Console.log of params:
Laravel:
public function getAnswers(Request $request)
{
$input = $request->all();
$question_objs = $input['questions'];
foreach ($question_objs as $question_answer_object) {
return $question_answer_object;
Response to Angular with: return $question_objs;
Response to Angular with: return $question_answer_object;
Looks like so far so good!
But if I try to access a property within laravel, like question_id:
return $question_answer_object['question_id'];
I get error:
"Illegal string offset 'question_id'
Laravel already parses the JSON,
// From Illuminate/Http/Request.php all() method:
if (! isset($this->json)) {
$this->json = new ParameterBag((array) json_decode($this->getContent(), true));
}
and when I return it, I can see it's an object. Why can't I access the properties? I've also tried json_decode without luck.
With JSON Decode:
$test = json_decode($question_answer_object, true);
return $test['question_id'];
This seems to work. But why?
Accessing the property on the object as such:
return $question_answer_object->question_id;
Gives the following error:
"Trying to get property of non-object"

Answer 1

The $question_answer_object['question_id'] variable is a string comprising JSON encoded data; to access that, you need to decode it first:
$decoded= json_decode($question_answer_object['question_id'], true);
return $decoded['question_id'];
If you're not sending the request as application/json, use $request->json().
You can get some information about this issues here.

Answer 2

Returned question is an object, not an array. You have to acces it with ->
return $question_answer_object->question_id;
