Flash Paper 仿百度文库的功能实现

具体是哪位大神发给我的,我就忘了,拿出来分享下吧<?php <br /> /*<br>     Description: FlashPaper文档转换,转换可打印的文档为FLASH格式并保存转换的相关信息到log_swfread表<br> <br>     * 使用FlashPaper服务需求<br>         1. 运行在Windows(xp/2003)服务器下<br>         2. 能调用系统命令exec<br>         3. 调用的文件目录必须可读可写<br>         4. 需要转换的文件类型，服务器必须安装相应的转换软件pdf安装 pdf 9.0, office安装2007,且必须是正版<br>         5. 服务器需要支持虚拟打印机功能<br>         6. 服务器的内容要足够大，最少4GB<br>         7. 在系统管理-站点管理-设置网站URL和访问URL一致<br> <br>     * 测试FlashPaer<br>         1.运行初始化中 初始化.bat文件 无任何错误即可(xp/2003)<br>         2.查看打印机文档中是否有打印机FlashPaer<br>         3.运行FlashPrinter.exe直接讲要转换的文件拖到此，如果能转换则软件安装无问题<br> <br>     * API调用方法<br>         1. 同步调用 -支持多文件同时转换，不支持执行时间检测和转换状态检测<br>             $flashPaper = A('Api.FlashPaper');<br>             $flashPaper->convertFile($uploadlist);<br>         2. 异步调用 -多文件上传需调用多次,支持执行时间检测和转换状态更新<br>             $url = $this->config['site_url'].'Api/FlashPaper/convertFile';<br>             foreach($uploadList as $data){<br>                 post($url,$data);<br>             }<br> <br>     * 注意<br>        1. 多文件同时转换<br>           - FlashPaper产生多个独立的进程,转换完毕后自动关闭经常和被调用的程序(尚未支持)<br>        2. 使用pptx/docx/xlsx转换速度快于2003格式<br> <br>     * 保持转换信息<br>         - 系统默认保存转换的文件名称,文件大小,文件类型,转换后保持地址,转换时间,转换运行时间和转换失败的错误信息<br>         - 默认保存的数据库表是log_swfread 保存的方式是execSaveInfo<br> <br> */<br> class FlashPaperAction extends Action<br> {<br>     public $flashpaper_url = '/Public/FlashPaper/FlashPrinter.exe'; // 应用程序路径<br>
