"Learning PHP" - An applied introduction to PHP: instead of a 3 hour tutorial that chugs through all the vocabulary and punctuation you need to memorize to be a PHP wizard, we'll build a community calendar and learn PHP by doing.
"PHP Forms Made Easy with HTML_QuickForm" - HTML_QuickForm is one of my favorite PEAR modules. It makes robust forms easy with excellent default value handling, automatic user input encoding, flexible validation, and a configurable layout engine. This talk tells you what you need to know to use HTML_QuickForm in your apps.
"Cleaning up SOAP" - SOAP is supposed to be simple, but usually it's pretty complicated and not always so interoperable. This talk tackles common SOAP-related tasks with PHP like: generating WSDL, creating custom datatypes, using SOAP headers and attachments, debugging, and adding authentication to a SOAP server or client.
