Examine Presentation

Aspose.Slides for PHP via Java allows you to examine a presentation to find out its properties and understand its behavior.

Check a Presentation Format

Before working on a presentation, you may want to find out what format (PPT, PPTX, ODP, and others) the presentation is in at the moment.

You can check a presentation’s format without loading the presentation. See this PHP code:

  $info = PresentationFactory->getInstance()->getPresentationInfo("pres.pptx");
  echo($info->getLoadFormat());// PPTX

  $info2 = PresentationFactory->getInstance()->getPresentationInfo("pres.ppt");
  echo($info2->getLoadFormat());// PPT

  $info3 = PresentationFactory->getInstance()->getPresentationInfo("pres.odp");
  echo($info3->getLoadFormat());// ODP

Get a Presentation Properties

This PHP code shows you how to get a presentation’s properties (information about the presentation):

  $info = PresentationFactory->getInstance()->getPresentationInfo("pres.pptx");
  $props = $info->readDocumentProperties();
  echo($props->getCreatedTime());
  echo($props->getSubject());
  echo($props->getTitle());
  # ..

You may want to see the properties under the DocumentProperties class.

Update a Presentation Properties

Aspose.Slides provides the PresentationInfo.updateDocumentProperties method that allows you to make changes to a presentation’s properties.

This PHP code shows you how to edit a presentation’s properties:

  $info = PresentationFactory->getInstance()->getPresentationInfo("pres.pptx");
  $props = $info->readDocumentProperties();
  $props->setTitle("My title");
  $info->updateDocumentProperties($props);
