PHP array_column with foreach loop - php

Question

I have a table from which i am fetching some columns
$records=Table::select('id','text','type')->paginate(250)->toArray();
$data=$records->['data'];
I am getting output as :-
array:250 [
0 => array:4 [
"id" => 1
"text" => "text1"
"type" => "A"
]
1 => array:4 [
"id" => 1
"text" => "text2"
"type" => "B"
]
2 => array:4 [
"id" => 1
"text" => "text3"
"type" => "C"
]
3 => array:4 [
"id" => 2
"text" => "text4"
"type" => "A"
]
4 => array:4 [
"id" => 2
"text" => "text5"
"type" => "B"
]
5 => array:4 [
"id" => 2
"text" => "text6"
"type" => "C"
]
6 => array:4 [
"id" => 3
"text" => "text7"
"type" => "A"
]
7 => array:4 [
"id" => 3
"text" => "text8"
"type" => "B"
]
8 => array:4 [
"id" => 3
"text" => "text9"
"type" => "C"
]....
]
I want to convert it into array of objects/array of arrays where results of same id should merge in such a way that value of "type" should be key and value of "text" as value. Below is a sample of expected result:-
array:20 [
{
"id" => 1
"A" => "text1"
"B"=>"text2"
"C"=>"text3"
}
{
"id" => 2
"A" => "text4"
"B"=>"text5"
"C"=>"text6"
}
{
"id" => 3
"A" => "text7"
"B"=>"text8"
"C"=>"text9"
}...
]
I have tried using array_column.
$sortedRecords = array_column($data, 'text','type');
Using array_column, i am able to convert value of "type" as key and "text" value as its value. But i am not able getting how to display id also and how to loop for each distinct id as it is displaying result of only last id.

Answer 1

Following logic might help you on your way. The source array is called $arr, the result array $newArr.
The snippet runs through all unique id's in the source array and accumulates the accompanying text values.
$newArr = [];
$ids = array_values(array_unique(array_column($arr, 'id')));
foreach ($ids as $key => $id) {
foreach ($arr as $value) {
if ($value['id'] === $id) {
$newArr[$key]['id'] = $id;
$newArr[$key][$value['type']] = $value['text'];
}
}
}

You can get information in groups with group By and perform any operation you need
$records = Table::select('id','text','type')->groupBy('type')->paginate(20)->toArray();
