テストデータ生成スクリプト

EC-CUBE 2.0.x 用のテストデータ生成スクリプトです.

cli 版の PHP を使用し, このスクリプトを実行することにより, テスト用の商品データを自動生成します.

• 実行時間の計測に PHP5 のみサポートされている関数を使用しています. PHP4 を使用した場合は, 実行時間の計測ができません.
• Pear::DB に依存していますので, include_path に Pear::DB が必要です.
• 下記の PHPコードをコピーして, CreateEcCubeData.php というファイル名で保存して下さい.
• 先頭の #!/usr/local/bin/php というパスを環境に合わせて編集して下さい.
• define の値を環境に合わせて編集して下さい.
