当我运行吹码时:
/*** 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;
它给了我一个例外:
致命错误:未捕获的异常'com_exception',消息'来源: Microsoft Office PowerPoint 2007 说明: PowerPoint无法打开该文件。 “在E:\ wamp \ www \ temp \ video_conversion.php:107堆栈跟踪:#0 E:\ wamp \ www \ temp \ video_conversion.php(107):variant-> Open('E:\ wamp \ www \ tem ...')在第107行的E:\ wamp \ www \ temp \ video_conversion.php中抛出#1 {main}
我无法弄清问题是什么。

这是一个问题是由于以下因素。
答案 1 :(得分:3)
在您的错误中,您会看到以下消息:PowerPoint could not open the file.' in E:\wamp\www\temp\video_conversion.php:107
PHP用户是否拥有文件E:\wamp\www\temp/a.pptx
的权限?
尝试更正斜杠:E:\wamp\www\temp\a.pptx
因为/
通常是指选项或参数。
在一天结束时,它似乎是权限错误,位置问题或类似问题,导致无法访问该文件。您可以使用fopen
或file_get_contents
打开文件吗?

尝试使用com类:
COM类参考: - http://us2.php.net/manual/en/class.com.php

<body>
<?
$ppApp = new COM("PowerPoint.Application");
$ppApp->Visible = True;
$strPath = realpath(basename(getenv($_SERVER["SCRIPT_NAME"]))); // C:/AppServ/www/myphp
$ppName = "MySlides.ppt";
$FileName = "MyPP";
//*** Open Document ***//
$ppApp->Presentations->Open(realpath($ppName));
//*** Save Document ***//
$ppApp->ActivePresentation->SaveAs($strPath."/".$FileName,17); //'*** 18=PNG, 19=BMP **'
//$ppApp->ActivePresentation->SaveAs(realpath($FileName),17);
$ppApp->Quit;
$ppApp = null;
?>
PowerPoint Created to Folder <b><?=$FileName?></b>

或试试这个:
$powerpnt = new COM("powerpoint.application") or die("Unable to instantiate Powerpoint");
$presentation = $powerpnt->Presentations->Open(realpath($file), false, false, false) or die("Unable to open presentation");
foreach($presentation->Slides as $slide)
{
$slideName = "Slide_" . $slide->SlideNumber;
$exportFolder = realpath($uploadsFolder);
$slide->Export($exportFolder."\\".$slideName.".jpg", "jpg", "600", "400");
}
$powerpnt->quit();
