Enabling an extention in PHP is not only by including it into php.inifile, you need to recompile your PHP installation with package support being enabled, in order to do this for bz2, you have to execute the needed pecl command:
在 PHP 中启用扩展不仅是通过将其包含到php.ini文件中，您还需要在启用包支持的情况下重新编译 PHP 安装，为了对 bz2 执行此操作，您必须执行所需的 pecl 命令：
pecl install bz2
To install peclyou have to install pearand phpize, on a debian based system, the following command should be sufficint:
要安装，pecl您必须在基于 debian 的系统上安装pear和phpize，以下命令就足够了：
apt-get install php5-dev php-pear
Finally you need to add the new extension to php.inifile, Don't forget to reload your web server after that.
最后，您需要将新扩展名添加到php.ini文件中，之后不要忘记重新加载您的 Web 服务器。
