Parsing a nested array where key is a float in php - php

Question

I have the following query that I need to get a value from a nested array. I'm using laravel 5.4 in case that matters.
$usersstyle = DB::connection('mysql2')
->table('wp_rg_lead_detail')
->where('lead_id', $collection->id)
->get();
dd($usersstyle);
This has an output of:
Collection {#396 ▼
#items: array:49 [▼
0 => {#406 ▶}
1 => {#407 ▶
18 => {#428 ▼
+"id": 655
+"lead_id": 67
+"form_id": 8
+"field_number": 51.0
+"value": "Yes"
}
19 => {#429 ▼
+"id": 656
+"lead_id": 67
+"form_id": 8
+"field_number": 6.1
+"value": "Sleeveless"
}
20 => {#430 ▼
+"id": 657
+"lead_id": 67
+"form_id": 8
+"field_number": 6.2
+"value": "Jacket"
}
21 => {#431 ▼
+"id": 658
+"lead_id": 67
+"form_id": 8
+"field_number": 6.3
+"value": "Cardigan"
}
22 => {#432 ▶}
I have tried the following, but it returns the 1st instance of the field_number, and ignores the 6.2 and 6.3. How do I do this and keep all the floats as keys.
$keyed = $usersstyle->keyBy('field_number')->all();
I want to get something like the below. With out a foreach loop to display that.
echo $6.3->value;
with the result being Cardigan
I have also used
$grabvalues = $usersstyle->whereIn('field_number', 80.3)->toArray();
this returns an array or if i drop the toArray a collection that I still need to loop through to get the value

Answer 1

Try this : This doc may help you .
$plucked = $usersstyle->pluck('field_number', 'value');
$plucked->all();
Another way :
$fieldValue = $usersstyle->map(function ($users) {
return collect($users->toArray())
->only(['field_number', 'value'])
->all();
});

Well after a bunch of test.. Here is the answer I came up with that worked for me. if someone knows how to write this better please submit.
$usersstyle = DB::connection('mysql2')
->table('wp_rg_lead_detail')
->where('lead_id', $collection->id)
->get()
;
$newkeys = $usersstyle->pluck('field_number');
$values = $usersstyle->pluck('value');
$result = $newkeys->combine($values)->toArray();
dd($result["6.1"]);
