Merge arrays on Laravel - php

Question

I'm new in Laravel and I'm trying to merge or join to arrays in one array, which have a one-to-many relationship.
These are the models:
class GroupMenu extends Model
{
public function optionmenu()
{
return $this->hasMany(OptionMenu::class, 'groupmenu_id');
}
}
class OptionMenu extends Model
{
public function groupmenu()
{
return $this->belongsTo(GroupMenu::class, 'groupmenu_id');
}
}
Also I have this function which returns the following arrangement.
public function getOptionMenus()
{
$optionmenu = OptionMenu::whereHas('tipousuario', function ($query) {
$query->where('tipousuario_id', session()->get('tipousuario_id'))->orderBy('orden');
})->get()->toArray();
return $optionmenu;
}
The output is like that:
array:17 [▼
0 => array:2 [▼
"id" => 1
"groupmenu_id" => 1
]
1 => array:2 [▼
"id" => 2
"groupmenu_id" => 1
]
2 => array:2 [▼
"id" => 3
"groupmenu_id" => 1
]
3 => array:2 [▼
"id" => 4
"groupmenu_id" => 2
]
4 => array:2 [▼
"id" => 5
"groupmenu_id" => 2
]
My problem is that I want to have an array where for each groupmenu has within it the array of the optionmenu, something like that:
0 => array:2 [▼
"id" => 1
"optionmenu" => array:3[array of all the optionsmenu that belongs to the groupmenu]
]
1 => array:2 [▼
"id" => 2
"optionmenu" => array:1[array of all the optionsmenu that belongs to the groupmenu]
]

Answer 1

If you want to get all GroupMenu records with related OptionMenu records without any constraint
$data = GroupMenu::with('optionmenu')->get();
However if you want to constrain the related OptionMenu records for each GroupMenu parent record based on the id of tipousuario - which you get from session as shown in your question then you can try something like
$data = GroupMenu::with([
'optionmenu' => fn($query) =>
$query->whereHas('tipousuario', fn($q) =>
$q->where('tipousuario_id', session()->get('tipousuario_id'))->orderBy('orden')
)
])->get();
