「[PHP] 404レポート（PHP版）Ver.0.05→0.08」（「[PHP] 404レポート（PHP版）」）に「CakePHP with CloudFlare」の内容を追加してバージョンアップした。
バージョンアップと言ってもただそれを追加しただけではあるが、未だに動いてたりするので・・。

動作確認
もはやどのように動作するかも忘れてしまっている部分があって、意図的に発生させた404ではエラーがレポートされなかった。
そういえばエラー報告抑制のためのロジックがあったようなかなったような。
ひとまずデバッグモードにして値を確認したところ、正しい内容を表示しているので、よいと思う。たぶん。
