Laravel - set array just with values - php

Question

I'm trying to send an email to multiple emails, so I did a query to my users tables but the result is an array with keys that don't work mail->to().
I need an array like this: $owners = ['myoneemail#esomething.com', 'myother#esomething.com','myother2#esomething.com']; from database.
My query:
$owners = DB::table('users')->select('email')->where('active', 1)->where('userType', 1)->get();
I also try use ->toArray() but comes with keys.
Email:
Mail::send('email-view', $data, function($message) use ($data, $owners)
{
$message->from('no-reply#email.pt' , 'FROM');
$message->to($owners)->subject('subject');
});

Answer 1

$owners = DB::table('users')->where('active', 1)->where('userType', 1)->pluck('email')->toArray();

Answer 2

You can use ->pluck(), like this:
$owners = DB::table('users')->select('email')->where('active', 1)->where('userType', 1)->get();
$emailList = $owners->pluck('email');

Answer 3

$owners = DB::table('users')->where('active', 1)->where('userType', 1)->pluck('email');
or
$owners = User::where('active', 1)->where('userType', 1)->pluck('email');
here User is your model name

Answer 4

First of all, the where condition is not proper in your query builder code.
It has to be like:
$query->where([
['column_1', '=', 'value_1'],
['column_2', '<>', 'value_2'],
[COLUMN, OPERATOR, VALUE],
...
])
You can use pluck() to get the list in Laravel 5.
All collections also serve as iterators, allowing you to loop over them as if they were simple PHP arrays:
foreach ($owners as $owner) {
echo $owner->filed_name;
echo $owner->filed_name;
...
}
There is no restriction for using the core PHP code while using a PHP framework. You may refer the official PHP Arrays Manual page to work with the language construct.
If you need to convert JSON to array, use:
json_decode($owners);
