Seminar Presentations
I have presented quite a few seminars at the Sydney PHP user's group over the years, and here are links to some of the presentations that I've given.
Past Presentations

Creating Excel Files with PHP
In this presentation I demonstrated two techniques of creating and reading excel files (proper excel files, not the csv type!). One technique combines PHP with VBA (via COM objects) to manipulate an Excel File. The other technique uses a third-party library I came across that does the same without the need for VBA or COM objects
Creating pdf files: An Introduction
In this presentation I demonstrated the fpdf library, a royalty free php library that can be used to generate pdf documents.
Charting with PHP
This presentation demonstrated the power of the gd2 PECL extension and a couple of PEAR packages. The presentation concentrated on developing the chart shown on the right.
Sending and Receiving Emails with PHP
In this presentation I demonstrated how to send basic emails, HTML emails, emails with attachments etc. During the second half of the presentation I showed the audience how PHP can 'read' emails.
Sending SMS text messages to Mobile Phones with PHP
A couple of my students did this presentation inconjunction with getting an article on this topic published in a major computing magazine.
Upcoming Presentations...
Dates for these seminars have not been confirmed, but they are likely to be held sometime in 2008. Check the Sydney PHP user's group or my homepage for updates.
Creating rtf and Word documents with PHP
Similar to the 'Creating Excel Files with PHP' seminar, except this time my focus is on creating Word documents and rtf files.
