php如何实现ppt转图片以及php调用com组件问题的详细介绍

 PHP 调用com组件将ppt转为图片。

需要在php.ini中开启

extension=php_com_dotnet.dll
com.allow_dcom = true

测试代码如下：

<?php
$powerpnt = new COM("powerpoint.application") or die("Unable to instantiate Powerpoint");
$file=&#39;1.ppt&#39;;
echo realpath($file);

$addr = $_SERVER[&#39;DOCUMENT_ROOT&#39;].&#39;/ppt/1.ppt&#39;;
echo $addr;
$presentation = $powerpnt->Presentations->Open($addr, false, false, false) or die("Unable to open presentation");


$presentation->Fonts->Replace(&#39;黑体&#39;,&#39;幼圆&#39;);
$presentation->Fonts->Replace(&#39;MS Gothic&#39;,&#39;幼圆&#39;);
$presentation->Fonts->Replace(&#39;方正粗倩简体&#39;,&#39;幼圆&#39;);
$presentation->Fonts->Replace(&#39;方正小标宋简体&#39;,&#39;幼圆&#39;);
$presentation->Fonts->Replace(&#39;Arial Black&#39;,&#39;幼圆&#39;);
$presentation->Fonts->Replace(&#39;华文中宋&#39;,&#39;幼圆&#39;);
$presentation->Fonts->Replace(&#39;Arial Unicode MS&#39;,&#39;幼圆&#39;);
$presentation->Fonts->Replace(&#39;方正细圆简体&#39;,&#39;幼圆&#39;);
$presentation->Fonts->Replace(&#39;Times New Roman&#39;,&#39;幼圆&#39;);


foreach($presentation->Fonts as $c)
{
	echo $c->name."<br />";
	//echo $c->Replace(&#39;&#39;,&#39;&#39;);
}


foreach($presentation->Slides as $slide)
{
$slideName = "Slide_" . $slide->SlideNumber;
$uploadsFolder = &#39;iii&#39;;
$exportFolder = realpath($uploadsFolder);
$slide->Export($exportFolder."//".$slideName.".jpg", "jpg", "1920", "1080");
}
$presentation->Close();
$powerpnt->Quit();
$powerpnt = null;
?>

在win7上跑，没问题，放到2008上面出现错误，有一种exception叫unknown...

解决方案：

cmd -》 dcomcnfg
