PHP7調査(10)名前空間のuseをまとめて書けるようになった

Last updated at Posted at 2015-04-11

PHP7から、名前空間を使うときに複数のuseを中カッコでまとめて書くことができます。

具体的には次のように書けるようになりました。

<?php
use Symfony\Component\Console\{
    Input\InputInterface,
    Input\InputArgument,
    Input\InputOption,
    Output\OutputInterface,
    Output\ConsoleOutputInterface
};

これまで、特に大物ライブラリを使うときにuseが長大になる傾向があったので、これは良い変更ですね。

ちなみに中カッコのネストはできません。
