Laravel - Pluck multiple columns - laravel

Question

I need to pluck two columns name and score from my table corporate_objectives and put it in my graph chart. I'm having two different behavior and I can't seem to get my desired result.
1st code
$getNameAndScore = CorporateObjective::pluck('name');
foreach($getNameAndScore as $key => $item) {
$corporateObjective[] = [$item, '('.$key.'%)'];
}
Result:
"xAxis": [
[
"PEOPLE DEVELOPMENT",
"(0%)"
],
[
"OPTIMUM SYSTEMS AND PROCESSES",
"(1%)"
],
[
"CUSTOMER MANAGEMENT",
"(2%)"
],
[
"REVENUE GROWTH",
"(3%)"
]
],
2nd code
$getNameAndScore = CorporateObjective::pluck('name', 'score');
foreach($getNameAndScore as $key => $item) {
$corporateObjective[] = [$item, '('.$key.'%)'];
}
Result:
"xAxis": [
[
"REVENUE GROWTH",
"(25%)"
]
],
I'm getting all the correct name but the incorrect score in my first code. On my second code, I'm getting the correct name and score but all data is not being pulled out. I wanted to achieve the first code with all the correct score from the second code.
EDIT:
This is how my database looks like
id | name | score
1 PEOPLE DEVELOPMENT 25
2 OPTIMUM SYSTEMS AND PROCESSES 25
3 CUSTOMER MANAGEMENT 25
4 REVENUE GROWTH 25
Is there another way other than pluck? It seems like pluck merges / filters all data with the same value.

Answer 1

This is the correct output of your code. There is no problem here
$getNameAndScore = CorporateObjective::pluck('name', 'score');
foreach($getNameAndScore as $key => $item) {
$corporateObjective[] = [$item, '('.$key.'%)'];
}
How does work pluck here is description
If duplicate keys exist, the last matching element will be inserted into the plucked collection:
$collection = collect([
['brand' => 'Tesla', 'color' => 'red'],
['brand' => 'Pagani', 'color' => 'white'],
['brand' => 'Tesla', 'color' => 'black'],
['brand' => 'Pagani', 'color' => 'orange'],
]);
$plucked = $collection->pluck('color', 'brand');
$plucked->all();
// ['Tesla' => 'black', 'Pagani' => 'orange']

So I just made an alternative way of doing it and it might help other people. If there is a more proper way or cleaner way of doing it, please feel free to correct my answer.
$getNameAndScore = CorporateObjective::pluck('name');
foreach($getNameAndScore as $item) {
$key = CorporateObjective::where('name', $item)->value('score');
$corporateObjective[] = [$item, '('.$key.'%)'];
}
return response()->json([
'xAxis' => $corporateObjective,
]);
Result
"xAxis": [
[
"PEOPLE DEVELOPMENT",
"(25%)"
],
[
"OPTIMUM SYSTEMS AND PROCESSES",
"(1%)" // I changed the value in the database and it works
],
[
"CUSTOMER MANAGEMENT",
"(22%)" // I changed the value in the database and it works
],
[
"REVENUE GROWTH",
"(25%)"
]
],
