Array does not return value using a static method function

Question

In this static function all variables return their respective values, except $funcionario which is an array.

Where am I going wrong?

class Dtb{

    public static $funcionarios =['M','G','N','I'] ;
    public static $atividades='Sistemas';
    public static $temp=12;

}


echo Dtb::$funcionarios;
echo Dtb::$atividades;
echo Dtb::$temp;

Answer 1

To print a array it is necessary to format it, one of the ways is the print_r():

class Dtb {
    public static $funcionarios = ['M','G','N','I'] ;
    public static $atividades = 'Sistemas';
    public static $temp = 12;
}
echo print_r(Dtb::$funcionarios);
echo Dtb::$atividades;
echo Dtb::$temp;

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
