$my_array =[1,2,3,4,5];
$even_numbers = array_filter($my_array, function ($number){ return $number % 2==0; });
The array_filiter function receives the array to be filter as fisrt argument, and a callback defining the filter predicate as its second.

need to put one more element to show in controller laravel, today 'status_viagem','=','VIAGEM' works finne but need´s 'VIAGEM' and 'DESCARGA'.
My controller:
public function listaPainel(Request $request)
{
$lista = Cco::where('status_viagem','=','VIAGEM')->get();
$data['lista'] = $lista;
return view('rast.lista_painel', $data);
}
Your question is not clear. I am guessing you want to compare with more data in where condition. In this case, you may need like this:
$lista = Cco::whereIn('status_viagem', ['VIAGEM', 'DESCARGA'])->get();
You need to be more clear about your problem.

I have a post value named $_POST['John'] and I want to insert the post name "John" into a variable but not its value. How can I achieve this? Code Sample:
$_POST['John'] = "value";
array_keys is PHP function which is returning the keys from an array, you have only single array than we can use 0 as the key. if you have more than one array element you can use loop.
You can use array_keys as you mentioned there is one parameter use
$a = array_keys($_POST)[0];

When we pass an array as an argument to a function, what actually gets passed?
Someone told me that it is "Base address of the array"? but I am not sure about it. How this array is processed then?
this is the answer: Are arrays in PHP passed by value or by reference?
