アマゾンウェブサービスを介してコンテンツを取得しています（製品の説明など）。アマゾンからのコンテンツはしばしば非常に不十分にマークアップされるので、それは私のウェブページのレイアウトを台無しにすることになります。そこで、HTMLTidyを使用してコンテンツを「サニタイズ」する機能を考案しました。
奇妙なことに、アプリケーションとは別にテストすると、すべてが正常に機能しているように見えます。しかし、私のアプリケーション（CodeIgniterで実行）では、関数は奇妙な文字を返すようです。
以下のコードは私のテストスクリプトです。必要だと思うものを出力しています。
私のアプリケーションでは、データベースから説明を取得し、サニタイズしてから、Webページに表示します。たとえば、サニタイズ後document’s（以下の例でこの単語を見ることができます）はdocument’s（ここでも、実際のアプリケーションでのみ、テストコードではありません。両方の機能は同じです）になります。
なぜ何かアイデアはありますか？これが私のテスト関数です：
$amazon_content = <<<AMAZON
