Where are the fields when creating a new object?

Question

PHP

I want to do like this:

$company = new Company;
               $company['country_id'] = (new Country)->getId('russia');

               return response()->json($company);

And you have to do this:

$company = new Company;
               $company['name'] = null;
               $company['website'] = null;
               $company['country_id'] = (new Country)->getId('russia');
               $company['city_id'] = null;
               $company['other_country'] = null;
               $company['other_code'] = null;
               $company['other_city'] = null;
               $company['address'] = null;
               $company['phone'] = null;

               return response()->json($company);

Because in the first case it passes an empty object, and I need fields for the date in json. It is not clear then what is the point of new Сompany, then I can simply do $company = {};
Maybe something needs to be added to new Сompany so that Laravel automatically creates fields from the table in the object?

Answer 1

$handle = fopen($dir . $minus, 'r');
while (($res = fgets($handle)) != FALSE) {
    if ($res != 0) {
        $array_minus[trim($res)] = true; // <- this
    } else {
        break;
    }
}
fclose($handle);
// сравнение
foreach ($array_source as $value) {
    if (!isset($array_minus[$value])) { // <- this
        $array_result[] = $value;
    }
}

file_put_contents("result.txt", implode(PHP_EOL, $array_result));

Two important lines are marked with comments.
On two files of 150k lines, it worked for me in 0.333s
PS array_diff, proposed by Denis Akimkin , is much better in readability with comparable performance, so it's better to use it.

Answer 2

No way. This is php you need either something like HHVM or php7 or another programming language

Answer 3

the fields of the object "name" and others are implemented through magic, and in fact the object does not have them.
why don't you use
$company->toJson();
