php7.2 waste alternatives to each method

In the 7.2 version will prompt obsolete, you can use foreach replace each method, you can also modify their own each alternative method:

function func_new_each(&$array){
    $res = array();
    $key = key($array);
    if($key !== null){
        next($array);
        $res[1] = $res['value'] = $array[$key];
        $res[0] = $res['key'] = $key;
    }else{
        $res = false;
    }
    return $res;
}
