HomeBackend DevelopmentPHP TutorialPHP 实现Word,excel等转换pdf

最近做一个项目,需要将用户上传的word,excel文档转成PDF文档保存并打印,在网上找了很多资料,并不全面,所以自己写了一份比较全面的教程来分享。

下面是操作步骤:

1、        安装免费的openOffice软件,请至openoffice.org下载最新版本。

2、        JDK支持,请自行搜索下载最新版本JDK。

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,选择

在这两项上分别点击右键属性,打开属性面板如下图:

选择安全选项卡,分别在启动和激活权限和访问权限两项上点自定义,添加Everyone的权限。

选择标识选项卡,选择交互式用户。

 

4、        安装完openOffice后,请先打开一次确认可以正常运行软件,然后退出后用命令行运行以下命令。

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

执行命令:

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

成功后即在后台运行了该软件。

 

5、        如果是php5.4.5以前版本,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。

6、        代码实现
