Need to create collection of keys with multiple values (Laravel 7.x) - arrays

Question

My first post here. I tried to search for an answer, but no luck, so here we go
Generally I cannot share with you with the exact code I'm working on :(
so here's the example one:
$collection = collect(['country' => 'Germany', 'city' => 'Berlin', 'month' => 'April']);
dd($collection);
//"country" => "Germany"
//"city" => "Berlin"
//"month" => "April"
$array1 = ['France', 'Paris', 'May'];
$array2 = ['Spain', 'Madrid', 'June'];
My question is - how to "add" those arrays (minding array1 and array2 order) so I end up with something like this?
dd($newCollection);
//output:
//"country" => ["Germany", "France", "Spain"]
//"city" => ["Berlin", "Paris", "Madrid"]
//"month" => ["April", "May", "June"]
OR
If there's a way to get all records from database and make one of the rows a key and a selection of them as values
Example
$users = User::get();
//this table has columns "full_name", "e-mail", "job", "birth_date", "city" and "password"
$collection = <<???>> //make column "full_name" as key and columns "e-mail", "job", "password" as values
dd($collection);
//output:
//"John Doe" => ["johndoe#mail.com", "Janitor", "topsecret"]
//"Jane Doe" => ["janedoe#mail.com", "teacher", "sercretpassword"]
Lifetime gratitude in advance for an answer... I've read Laravel's documentation many times and could not find a solution

Answer 1

I've got this
The solution for me looks like this:
$users = User::get();
//this table has columns "id", "full_name", "e-mail", "job", "birth_date", "city" and "password"
//I don't want to use all columns here
foreach($users as $user=>$value){
$full_name = $value->full_name;
$e-mail = $value->e-mail;
$job = $value->job;
$password -> $value->password;
$endresult[] = [$full_name, $e-mail, $job, $password];
}
$collection = collect($users->keyBy('id')->pluck('id'))->combine($endresult);
dd($collection);
//output:
// 1 => ["John Doe", "johndoe#mail.com", "Janitor", "topsecret"]
// 2 => ["Jane Doe", "janedoe#mail.com", "teacher", "sercretpassword"]
It looks terrible, but works like a charm. I needed to format this like so because in my project there are many foreign keys and I need to pagify my results, so to make it the easiest way possible I need to combine all values to one key (just like a row in csv) rather than call for every value in view
thank you for your support

Answer 2

You've technically asked two questions here. One where you merge a set of values into a key-value collection, and another where you simply limit the values from a set of key-value collections and key by the ID.
Given that you're really looking for an answer to the second question, by way of your answer, here's a cleaner way of doing it:
User::select('id', 'full_name', 'email', 'job', 'password')
->get()
->keyBy('id')
->map(function($user) {
return collect($user)->except('id');
});
