mapping join results as an array under related rows - php

Question

In laravel am using eloquent to get data from the database.
I have two tables 'questions' and 'options'
Am using the eloquent method to join 'options' to 'questions'
$questions = Question::join('options', 'options.question_id', 'questions.id');
return QuestionResource($questions);
This does return an expected collection of data, where the same question appear multiple times in the collection and each is joined with different options where the 'options.question_id' and 'question.id' are the same.
[
{
id: 1,
text: "Africa is a...?",
// joined option
question_id: 1,
value: "city",
answer: false
},
{
id: 1,
text: "Africa is a...?",
// joined option
question_id: 1,
value: "planet",
answer: false
},
{
id: 1,
text: "Africa is a...?",
// joined option
question_id: 1,
value: "continent",
answer: true
},
{
id: 2,
text: "Albert Heinstein was a...?",
// joined option
question_id: 2,
value: "comedian",
answer: false
},
{
id: 2,
text: "Albert Heinstein was a...?",
// joined option
question_id: 1,
value: "genius scientist",
answer: true
}
]
I want all options be nested under a key within the related question. Like
[
{
id: 1,
text: "Africa is a...?",
// joined options
options: [
{value: "city", answer: false},
{value: "planet", answer: false},
{value: "continent", answer: true}
]
},
{
id: 2,
text: "Albert Heinstein was a...?",
// joined options
options: [
{value: "comedian", answer: false},
{value: "genius scientist", answer: true}
]
}
]
Can I achieve this with laravel's eloquent or I'll have to apply an extra logic.

Answer 1

If you want to applie extra logic this code may help you
<?php
$combinedqst = array('id' => '','text'=> '','option'=> array('value' => array('value' => ,'' ), 'answer' => ''));
$ids = array('id' => , '');
//loop through questions array 1st loop for getting the question
foreach($questions as $question) {
$count = 0;
//check if question is already looped
if(!in_array($question["id"],$ids)){
//2end loop to get the opstions
foreach($questions as $question_check) {
if($question_check["id"] == $question["id"]){
if($count == 0){
$combinedqst["id"] = $question["id"];
$combinedqst["text"] = $question["text"];
}
$count = 1;
array_push($combinedqst["option"]['value'],$question_check['value']);
array_push($combinedqst["option"]['answer'],$question_check['answer']);
}
}
}
array_push($ids,$question["id"]);
}
vardump($combinedqst);
