関数やメソッドの引数の数を調べて、必須項目以外をnullで埋める際のtips

Last updated at Posted at 2021-08-31
class Hoge
{
    // 引数が多い
    public function getHogehoge(int $id, ?int $arg1, ?int $arg2, ?int $arg3, ?int $arg4, ?int $arg5)
    {
        return 'hogehoge';
    }
}

こんな引数が多いメソッド(しかも引数の数はたまに変わる)を使う際、$idだけ使い、それ以外nullで埋める場合の備忘録
そもそも引数をどうにかしろという言葉はぐっと堪えて下さい。。。

対応

// 関数の構造を格納
$refl = new \ReflectionClass("Hoge(HogeクラスのあるPath)");
// getHogehogeの引数の数を取得
$arg_num = $refl->getMethod("getHogehoge")->getNumberOfParameters();

$hoge = new Hoge();
// array_fillでnullを$arg_num - 1個分埋める
$products = $hoge->getHogehoge(1, ...array_fill(0, $arg_num - 1, null));
