The following code allows you to create powerpoint files in php.
<?php
$powerpnt = new COM("powerpoint.application");
//Creating a new presentation
$pres=$powerpnt->Presentations->Add();
//Adds the first slide. "12" means blank slide
$pres->Slides->Add(1,12);
//Adds another slide. "10" means a slide with a clipart and text
$pres->Slides->Add(2,10);
//Adds a textbox (1=horizontal, 20=left margin, 50=top margin, 300=width, 40=height)
$pres->Slides[1]->Shapes->AddTextbox(1,20,50,300,40);
//Adds a 16-point star (94=16 point star, 100=left margin, 200=top margin, 300=width, 300=height)
$pres->Slides[1]->Shapes->AddShape(94,100,200,300,300);
//Save the document as PPT file
$powerpnt->Presentations[1]->SaveAs("E:yeworld.ppt");
//And of course, quit Power Point
$powerpnt->quit();
//Give the user a download link
echo '
?>
