当我运行以下代码时:
/*** PPT to Image conversion ***/
$ppt_file = 'E:\wamp\www\temp/a.pptx';
$app = new COM("PowerPoint.application") or die("Unable to instantiate PowerPoint");
$app->Visible = true;
$app->Presentations->Open($ppt_file);
$app->Presentations[1]->SaveAs("E:/tmp/outdir",18);
$app->Presentations[1]->Close();
$app->Quit();
$app = null;
这个程序抛出了一个异常:
致命错误:Uncaught exception 'com_exception' with message '源:Microsoft Office PowerPoint 2007
描述:PowerPoint 无法打开文件。' in E:\wamp\www\temp\video_conversion.php:107 Stack trace: #0 E:\wamp\www\temp\video_conversion.php(107): variant->Open('E:\wamp\www\tem...') #1 {main} thrown in E:\wamp\www\temp\video_conversion.php on line 107
我无法确定问题所在。
