PHP 报错 Fatal error: Class 'COM' not found in
在 Win Server 08 往上搭载的 IIS 跑 php 性能提升不少，但还是觉得不太舒服,某日在调试一个win上的php生产环境时，一段php代码返回了错误：Fatal error: Class 'COM' not found in XXXXXXXXX
1、Fatal error: Class 'COM' not found in XXXXXXXXX
没发现 COM 类，php代码主要是调用一些系统的信息，初想应该是php没配置好，在stackoverflow找到答案，是讨论xampp的，要延伸开来，我加了几个要点：
★ php 根目录的 ext 文件夹下确保存有 php_com_dotnet.dll 这个文件
★ php.ini 确保有此语句
[PHP_COM_DOTNET] extension=php_com_dotnet.dll
2、[PHP_COM_DOTNET]extension=php_com_dotnet.dll
★ 开始 > 运行 > services.msc 回车 > 确保 COM+ Event System 的服务开启
在 PHP 5.4.5 版本之前是内置的，但往后版本中分离了。。。
