今更だけど、EthnaをPHP7にしてmysqliに対応した時のメモ

昔のコードのメンテナンスです（とか言ってみる

いい加減PHPも7になってEthnaはねーんじゃないの？って感じなのですが、これがまた意外と動くので使い続けたりしています。

ただ、preg_replaceのe修正子とmysql*系の関数が無くなったのでmysqli*に対応しないといけなくて、そのメモです。ちなみに、Ethna.phpをみると

/** バージョン定義 */
define('ETHNA_VERSION', '2.5.0-preview3');

とか書かれてたりします。

やらないといけないこと

• preg_replaceのe修正子の削除
• mysqliの適応
• =&を=にする。（これは一括置換とか使って）

以下コードの羅列です。

preg_replaceのe修正子対応
