recursive function transform nested array

Im my laravel project I have this nested array that needs to be updated (transformed - for the frontend):
array:2 [
0 => array:3 [
"entity_id" => 931
"entity" => "user"
"children" => array:2 [
0 => array:2 [
"entity_id" => 5
"entity" => "location"
]
1 => array:2 [
"entity_id" => 932
"entity" => "user"
]
]
]
1 => array:2 [
"entity_id" => 486
"entity" => "user"
]
]
EXPECTED ARRAY:
array:2 [
0 => array:4 [
"id" => 931
"text" => "Test User 1"
"type" => "user"
"children" => array:2 [
0 => array:3 [
"id" => 5
"text" => "Location 1"
"type" => "location"
]
1 => array:3 [
"id" => 932
"text" => "Test User 2"
"type" => "user"
]
]
]
1 => array:3 [
"id" => 486
"text" => "Test User 3"
"type" => "user"
]
]
I have created a recursive function for this job
public function getNewStructure($tree, &$output) {
foreach($tree as $data) {
$output[] = array(
'id' => $data['entity_id'],
'text' => $data['user'] === 'user' ? User::find($data['entity_id'])->name : Location::find($data['entity_id'])->name,
'type' => $data['entity']
);
$this->getNewStructure($data['children'] ?? [], $output);
}
return $output;
}
but it not returns as expected:
array:4 [
0 => array:3 [
"id" => 931
"text" => "Test User 1"
"type" => "user"
]
0 => array:3 [
"id" => 5
"text" => "Location 1"
"type" => "location"
]
1 => array:3 [
"id" => 932
"text" => "Test User 2"
"type" => "user"
]
1 => array:3 [
"id" => 486
"text" => "Test User 3"
"type" => "user"
]
]
How can I add the children to the $output array in the recursive function ???
I have tried by adding the children key:
$this->getNewStructure($data['children'] ?? [], $output['children']);
as when iterating again it will push the current array in the right place.... but is not working...
I fixed
public function getNewStructure($tree, &$output) {
foreach($tree as $data) {
$element = array(
'id' => $data['entity_id'],
'text' => $data['user'] === 'user' ? User::find($data['entity_id'])->name : Location::find($data['entity_id'])->name,
'type' => $data['entity']
);
if(is_array($data['children']) && count($data['children']) > 0) {
$element['children'] = $this->getNewStructure($data['children'], $element['children']);
}
$output[] = $element;
}
return $output;
}

Transform Laravel collection and group by key

I would like to transform a collection of object in laravel, but I can't figure it out how. I want to group the record by the type column, and set the grouped record under an array key value.
public function transformData()
{
$data = collect();
$matches = [ 'race', 'ethnicity'];
$attributes = Attribute::withTrashed()
->whereIn('type', $matches)
->get()
->groupBy('type');
$data->put(
$type, // to be the group key(like race)
[
'values' => $attributes->toArray(), // to be all the value with type race
]
);
dd(collect($data));
}
Here is what I'm getting:
Illuminate\Support\Collection^ {#2368
#items: array:1 [
"values" => array:2 [
"ethnicity" => array:2 [
0 => array:2 [
"id" => 1
"type" => "ethnicity"
]
1 => array:2 [
"id" => 2
"type" => "ethnicity"
]
]
"race" => array:2 [
0 => array:2 [
"id" => 6
"type" => "race"
]
1 => array:2 [
"id" => 7
"type" => "race"
]
]
]
]
#escapeWhenCastingToString: false
}
BUT I would like to return this instead:
Illuminate\Support\Collection^ {#2368
#items: array:1 [
"ethnicity" => array:2 [
"value" => array:2 [
0 => array:2 [
"id" => 1
"type" => "ethnicity"
]
1 => array:2 [
"id" => 2
"type" => "ethnicity"
]
]
]
"race" => array:2 [
"value" =>
0 => array:2 [
"id" => 6
"type" => "race"
]
1 => array:2 [
"id" => 7
"type" => "race"
]
]
]
#escapeWhenCastingToString: false
}

How to get value from unserialized data

I'm transforming my data into an array structure. Now I have the meta which already unserialized and I just need to take a specific value in meta.
Code
$item->meta;
$itm['attrs'] = #unserialize($item->meta);
$serial = #unserialize($item->meta);
$itm['product']['attrs'] = $itm['attrs'];
$itm['product']['serial'] = $serial['serial'];
Result
"product" => array:2 [
"attrs" => array:1 [
"serial" => array:1 [
0 => array:3 [
"id" => 848
"text" => "12345wf"
"trade_in" => 0
]
]
]
"serial" => array:1 [
0 => array:3 [
"id" => 848
"text" => "12345wf"
"trade_in" => 0
]
]
]
Expected Result
"product" => array:2 [
"attrs" => array:1 [
"serial" => array:1 [
0 => array:3 [
"id" => 848
"text" => "12345wf"
"trade_in" => 0
]
]
]
"serial" => "12345wf"
]
I'm not sure how to get the value and pass to the object.

How can get this?

0 => ""

If you need to 'flatten' the whole array, try array_map. The way it works is you define a function, that receives a single array item, transforms it and returns transformed value, then you pass that function to array_map in order to perform said transformation on all elements of the array:
function flatten($item){
return $item[0];
}
$original_array = Array(...); // assign your original array here
$flattened_array = array_map('flatten', $original_array);
Or using anonymous function syntax:
$flattened_array = array_map(function($item){return $item[0]}, $original_array);

ResultSetMapping addScalarResult associative array

In my project with Symfony2, I'm using Doctrine createNativeQuery, and I would like to get an associative array.
This is my code
$rsm = new ResultSetMapping;
$rsm->addScalarResult('id', 'id');
$rsm->addScalarResult('name', 'name');
$rsm->addScalarResult('phone_one', 'phoneOne');
$rsm->addScalarResult('phone_two', 'phoneTwo');
I have this result:
array:2 [
0 => array:4 [
"id" => "975"
"name" => "one name"
"phoneOne" => "122345556"
"phoneTwo" => "345566789"
]
1 => array:4 [
0 => array:4 [
"id" => "976"
"name" => "two name"
"phoneOne" => "122345556"
"phoneTwo" => "345566789"
]
]
It's posible this result?
array:2 [
0 => array:4 [
"id" => "975"
"name" => "one name"
"phones" => [
"phoneOne" => "122345556"
"phoneTwo" => "345566789"
]
]
1 => array:4 [
0 => array:4 [
"id" => "976"
"name" => "two name"
"phones" => [
"phoneOne" => "122345556"
"phoneTwo" => "345566789"
]
]
]
Thanks a lot
If that is the result you want, why not create a OneToMany for Users to Phones? I would highly suggest you do that.
