PHP使用COM 获取RTF内容

1. 需要在APP服务器上安装Office

2. 可能需要创建文件夹：Desktop
C:\Windows\SysWOW64\config\systemprofile\Desktop
3. 可能需要设置权限  component service，中找到 “Microsoft Office ….”中的属性，设置相关的权限

4. 可能需要设置Apache服务的登录用户名及密码

function getRTFtext($rtfFileName) {
    $result=‘‘;
    if (!is_file($rtfFileName)) {
        throw new ErrorException("File not found.");
    }
    $rtfFileName = realpath($rtfFileName);

    // Connect to Word
    if (!class_exists(‘COM‘)) {
        throw new ErrorException(‘COM extension is not enabled.‘);
    }

    $word = new COM("word.application");
    if (!$word) {
        throw new ErrorException(‘Unable to instantiate Word COM object.‘);
    }
    // Check the Word version.
    if ($word->Version < 12) {
        $word->Quit();
        $word = null;
        throw new ErrorException(‘The version of Word is too old.‘);
    }
    // $word->visible = 1;
    try {
        // Documents.Open: http://msdn.microsoft.com/en-us/library/office/ff835182%28v=office.14%29.aspx
        //$word->Visible=true;
        $word->Documents->Open($rtfFileName, FALSE, TRUE);

        $result= $word->ActiveDocument->content->Text;
        $word->ActiveDocument->Close(FALSE);
        //echo ‘‘.$test;
    } catch (Exception $e) {
        $word->Quit();
        $word = null;
        throw $e;

        $word->Quit();
        $word = null;
