无法在梨MDB2软件包中重新声明类mdb2_error

Question

I haven't install pear in my PC,instead I download the packages and unzip them to "libs" dictionary in my web-app.the structure of dictionary of my web-app is roughly like this:

web-app
  +-/backend
    +-/libs
      +-/peardb
        +-pear.php
        +-pear5.php
        +-mdb2.php
        +-/mdb2

The application works fine in my two PCs,but throws "Cannot redeclare class mdb2_error" error while it running in virtual host.

Answer 1

使用include_once / require_once通常可以解决此问题。
