Question

运行脚本后我的脚本出现问题 未捕获 带有消息“来源：Microsoft Word 描述：命令失败”的异常“com_exception”

并显示警报： http://imgur.com/HrDYrah

这是我的代码：

<?php
   $word = new COM("Word.Application") or die ("Could not initialise Object.");
   // set it to 1 to see the MS Word window (the actual opening of the document)
   $word->Visible = 0;
   // recommend to set to 0, disables alerts like "Do you want MS Word to be the default .. etc"
   $word->DisplayAlerts = 0;
   // open the word 2007-2013 document 
   $word->Documents->Open('C:\xampp\htdocs\Open_Office\test_4sk.docx');
   // save it as word 2003
   $word->ActiveDocument->SaveAs('C:\xampp\htdocs\Open_Office\newdocument.doc');
   // convert word 2007-2013 to PDF
   $word->ActiveDocument->ExportAsFixedFormat("C:\\xampp\htdocs\Open_Office\Main_PDF.pdf", 17, false, 0, 0, 0, 0, 7, true, true, 2, true, true, false);
   // quit the Word process
   $word->Quit(false);
   // clean up
   unset($word);
?>

将您的代码更改为：

<?php
   try{
       $word = new COM("Word.Application") or die ("Could not initialise Object.");
       // set it to 1 to see the MS Word window (the actual opening of the document)
       $word->Visible = 0;
       // recommend to set to 0, disables alerts like "Do you want MS Word to be the default .. etc"
       $word->DisplayAlerts = 0;
       // open the word 2007-2013 document 
       $word->Documents->Open('C:\xampp\htdocs\Open_Office\test_4sk.docx');
       // save it as word 2003
       $word->ActiveDocument->SaveAs('C:\xampp\htdocs\Open_Office\newdocument.doc');
       // convert word 2007-2013 to PDF
       $word->ActiveDocument->ExportAsFixedFormat("C:\\xampp\htdocs\Open_Office\Main_PDF.pdf", 17, false, 0, 0, 0, 0, 7, true, true, 2, true, true, false);
       // quit the Word process
       $word->Quit(false);
       // clean up
       unset($word);
   }catch(Exception $e){
       echo $e;
   }
?>

这样它就不会停止您的代码的执行，并且您可以在它发生时看到它。请注意，这里最理想的做法是将echo $e; 替换为实际的错误处理。
