わーい、すごーい

なんか気付いたら書いていたので、ここに供養します。

<?php
class Friends
{
    private $message = null;
    public function __construct()
    {
        $this->message = '';
    }

    public function wai()
    {
        $this->message .= "わーい\n";
        return $this;
    }

    public function sugoi()
    {
        $this->message .= "すごーい\n";
        return $this;
    }

    public function tanoshii()
    {
        $this->message .= "たのしー\n";
        return $this;
    }

    public function friends($skill)
    {
        $this->message .= '君は' . $skill . 'がとくいな、フレンズなんだね!!' . "\n";
        return $this;

    }

    public function __toString()
    {
        $message = $this->message;
        $this->message = '';
        return $message;
    }
}

echo (new Friends())
    ->wai()
    ->sugoi()
    ->tanoshii()
    ->friends('クソリプ');
