Powerpoint mit PHP

Wieder was interessantes aus der Gegend von PHP. Office 2007 baut ja inzwischen XML-basierte Dateien, d.h. das Erstellen von Office-Dokumenten ist erstaunlich einfach geworden. Nun gibt es neben der Excel-Klasse auch noch Powerpoint per PHP.

Ein Quellcodebeispiel gibt es hier: http://blog.maartenballiauw.be/post/2009/04/27/PHPPowerPoint-010-(CTP1)-released!.aspx

Das Zipfile das es zum Download gibt, enthält auch vier Testfälle. In meinem Fall musste ich noch den XMLWriter mit in PHP einkompilieren und danach noch ein paar Dateien und Verzeichnisse umbennen, da Linux bekanntlich sehr auf Groß- und Kleinschreibung achtet (PHPPowerpoint.php != PHPPowerPoint.php). Anyway, hier ein Beispielcode aus dem Zip und danach die generierte Powerpoint-Datei:

Die Testdatei geniert folgende Konsolenausgabe:

23:16:10 Create new PHPPowerPoint object
23:16:10 Set properties
23:16:10 Remove first slide
23:16:10 Create templated slide
23:16:10 Create a shape (rich text)
23:16:10 Create templated slide
23:16:10 Create a shape (rich text)

23:16:10 Write to PowerPoint2007 format
23:16:10 Peak memory usage: 3.5 MB
23:16:10 Done writing file.

Und dieses PDF hab ich aus dem Ergebnis erstellt (dazu brauch man dann wieder Powerpoint 2007, das kann die Klasse glaube ich nicht 🙂 )

Soweit so gut.
