用php找出Ppt文件的页码

Question

I want to get the page numbers of ppt files. My Code:

$filename = "aaa.ppt";
$word = new COM("Powerpoint.Application");
$word->PresentationDocument->Open($filename);
$wdStatisticPages = 2; // Value that corresponds to the Page count in the Statistics
echo $word->ActivePresentation->SlideParts->Count($wdStatisticPages);  
$word->ActivePresentation->Close();
$word->Quit();

But it gives error:

Fatal error: Uncaught exception 'com_exception' with message 'Unable to lookup `PresentationDocument': Unknown name. '

I got the answer, thanks Suyog for your efforts.

$filename = "aaa.ppt";
$power = new COM("Powerpoint.Application");
$power->visible = True;
$power->Presentations->Open(realpath($filename));
echo $power->ActivePresentation->Slides->Count;  
//$word->ActiveDocument->PrintOut();
$power->ActivePresentation->Close();
$power->Quit();
