我有两个需要读取的 rpt 文件，存储到 excel 和 mysql 数据库中。此外，我需要通过引用两个 rpt 文件中共有的唯一列来创建一个报告，该报告是两个 rpt 文件的连接结果。我以前读过 Excel、Exported Excel 和 Exported pdf，但这次我什至不知道如何开始。我尝试谷歌搜索并找到以下解决方案，但它将 rpt 转换为 pdf：

//- Variables - for your RPT and PDF 
//echo "Print Report Test"; 
$my_report = "D:\\Program Fiels\\xampp\\htdocs\\RPT\\RPT-list.rpt"; // 
//rpt source file 
$my_pdf = "D:\\Program Fiels\\xampp\\htdocs\\RPT\\RPT-list.pdf"; // RPT export to pdf file 
//-Create new COM object-depends on your Crystal Report version 
$ObjectFactory= new COM("CrystalReports10.ObjectFactory.1") or die ("Error on load"); // call COM port 
$crapp = $ObjectFactory-> CreateObject("CrystalRuntime.Application.10"); // create an instance for Crystal 
$creport = $crapp->OpenReport($my_report, 1); // call rpt report 

// to refresh data before 

//- Set database logon info - must have 
$creport->Database->Tables(1)->SetLogOnInfo("servername", "username", "password", "databasename"); 
//- field prompt or else report will hang - to get through 
$creport->EnableParameterPrompting = 0; 

//- DiscardSavedData - to refresh then read records 
$creport->DiscardSavedData; 
$creport->ReadRecords(); 


//export to PDF process 
$creport->ExportOptions->DiskFileName=$my_pdf; //export to pdf 
$creport->ExportOptions->PDFExportAllPages=true; 
$creport->ExportOptions->DestinationType=1; // export to file 
$creport->ExportOptions->FormatType=31; // PDF type 
$creport->Export(false); 

//------ Release the variables ------ 
$creport = null; 
$crapp = null; 
$ObjectFactory = null;

上面的代码也在寻找一个 COM 组件：CrystalReports10.ObjectFactory.1

我需要在 Linux 服务器上部署这个应用程序，所以我不确定这个 COM 组件是否在那里可用。请告诉我如何使用 Codeigniter 读取 rpt 并将数据存储到数据库和 Excel 中。
