No your webapp doesn't have to be under the GPL, just the other projects you are using that touch mysql client libs AFAIUI, it sounds like that would be mysql connector itself. The GPL requirement can leak up into the PHP interpreter but it can't leak any further. That's because although your PHP scripts and setup might direct PHP to talk to MySQL, but it could work as well with say postgreSQL with minor fiddles. So they can't claim that the existence of your scripts are entirely predicated on MySQL or its client libs: that's what they need to be able say to claim your scipt is a "derived work" of the MySQL client libs without any real independent life of its own. -Andy
