php|cruise was good, and this years offering from php|arch (php|tropics 2005) looks set to exceed it. I particularly enjoy a good conference; they're not just about learning new things, but also about getting together and sharing ideas, attendee:attendee, speaker:attendee and speaker:speaker.
I'm fortunate enough to be making two presentations, on the following topics:
PHP and Databases Grown-up: PDO
Speaking of grown up, following my talk is Dan Scott from IBM on using DB2 with PHP (hopefully your audience will be bigger this time Dan :-)
PHP Streams: Lucky Dip
I very warmly encourage you to attend the conference; the pricing is pretty good (and keep in mind that it's an all inclusive resort--that includes alcoholic beverages and food). If your boss isn't interested, but you really are, why not make php|tropics your vacation destination for the year?
