PHP4.xでPHP5.xの関数を使いたい場合に。upgrade.php

2007-10-27

upgrade.phpは、PHP4.xのサーバーでPHP5の関数を使いたい場合に、非常に便利なPHPファイルです。
現時点のZen-Cartでは、PHP5.xだと動作が怪しいので、PHP4.xで動作している方が多いでしょうから覚えておくと後で役に立つかもしれません。

基本的な使い方は、非常に簡単です。
http://upgradephp.berlios.de/からダウンロードしたupgrade.phpを適当なディレクトリへアップし

  <?php
     if (PHP_VERSION < "4.4.0") { include(".../upgrade.php"); }
  ?>

とするだけで、OK。Zen-Cartの場合は、
includes/functions/extra_functions/
にアップロードするだけで自動的に読み込まれます。

これにより以下の関数が使えるようになるようです。(v15-READMEより)
