Convert two dimentional array into the json object in Laravel - json

Question

I am converting a two-dimensional array into a JSON object.
Now my controller returning this output:
[
[
{
"id": 1,
"title": "V1",
"project_id": 1
}
],
[]
]
Want to convert it like:
[
{
"id": 1,
"name": "Laravel"
},
{
"id": 2,
"name": "Wordpress"
}
]
My controller code:
$user = auth()->user();
$projectVersions = array();
foreach($user->projects as $project)
{
$projectId = $project->pivot->project_id;
$projectVersions[] = Version::where('project_id', $projectId)
->where('created_by', $user->id)
->get();
}
return $projectVersions;
When I am using below code which is suggested by #John Lobo, it is returning below output:
{
"id": 2,
"name": "Hadayat Niazi",
"email": "niazicr801#gmail.com",
"is_admin": 0,
"email_verified_at": null,
"created_at": "2021-06-11T15:13:00.000000Z",
"updated_at": "2021-06-11T15:13:00.000000Z",
"projects": [
{
"id": 1,
"name": "Laravel",
"pivot": {
"user_id": 2,
"project_id": 1
},
"versions": [
{
"id": 1,
"title": "V1"
}
]
}
]
}
Displaying the user projects and versions:
Again I am updating the code for #John Lobo, he want to look the output
$user = User::with(['projects', 'projects.versions'])
->find(auth()->user()->id);
$result = $user->projects->map(function ($project) {
return [
$project->versions,
];
});
return $result;
Output the code
[
[
[
{
"id": 1,
"title": "V1",
"project_id": 1,
"version": "1.22",
"created_by": 2,
"is_publish": 0,
"feature": "<b>In this ipdate asdsdasd</b>",
"bug_fix": "<p><b>sdfdffffffffff</b></p>",
"created_at": "2021-06-12T08:08:21.000000Z",
"updated_at": "2021-06-12T08:08:21.000000Z"
},
{
"id": 2,
"title": "v2",
"project_id": 1,
"version": "2.12",
"created_by": 2,
"is_publish": 0,
"feature": "adsdasdsadas",
"bug_fix": "sddasdas",
"created_at": null,
"updated_at": null
}
]
],
[
[]
]
]

Answer 1

In controller you can do the following.if you have relation in project model called version
$projectVersions=User::with(['projects','projects.version'])->find(auth()->user()->id);
return $projectVersions->projects;
I believe Project model has below relationship
public function version(){
return $this->hasMany(Version::class);
}
Updated
$user=User::with(['projects','projects.versions'])->find(auth()->user()->id);
$result = $user->projects->map(function ($project) {
return $project->versions;
});
dd($result);

Use like below
$json = json_encode($responseOfController);
echo "<pre>";print_r($json);die;
