PHP和COM
如果你是一名冒险份子,而且你正在使用CGI、ISAPI或Apache模块版本的Windows系统上运行着PHP,那么你也可以获得系统的COM功能。现在,解释COM(微软的组件对象模型)的工作留给了微软和那些大部头的图书来完成。然而,知道点COM也没什么错,下面有一个普通的(没有双关语,针对很普通)代码小片断。
这代码小片断使用PHP在后台启动Microsoft Word、打开一个新文件、键入一些文本、保存该文件然后关闭应用程序:
// create a reference to a new COM component (Word) $word = new COM("word.application") or die("Cant start Word!");
// print the version of Word thats now in use echo "Loading Word, v. {$word->Version} ";
// set the visibility of the application to 0 (false) // to open the application in the forefront, use 1 (true) $word->Visible = 0;
// create a new document in Word $word->Documents->Add();
// add text to the new document $word->Selection->TypeText("Testing 1-2-3...");
//save the document in the Windows temp directory $word->Documents[1]->SaveAs("/Windows/temp/comtest.doc");
// close the connection to the COM component $word->Quit();
// print another message to the screen echo "Check for the file..."; ?>
假设你正在运行一个内联网Web站点,该站点把数据存放在Microsoft SQL Server数据库内,你的用户需要Excel格式的数据。那么,你可以让PHP执行必要的SQL查询并且格式化输出结果,然后使用COM启动Excel,把数据传输给它,最后再把文件存储到用户的桌面系统内。
