1、安装免费的openOffice软件

2、需要JDK支持

3、安装完openOffice后，在开始--运行中输入Dcomcnfg打开组件服务。在组件服务—计算机—我的电脑—DCOMP配置中

 

 

 

 

 

 

 

 

4、 先到安装目录下，例如：C:\Program Files\OpenOffice 4\program\

cmd -> soffice -headless-accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

 

5、需要在php.ini里把com.allow_dcom = true打开，即去掉前面的分号。如果是以后版本，需要在php.ini 里增加一行扩展extension=php_com_dotnet.dll，然后检查php的ext目录中是否存在该dll文件，如果没有请自行下载对应版本的dll。然后重启apache或IIS服务器。
