How does the FOSS exception for MySQL connectors apply to code written in PHP or Python?

Question

I have looked all over and can't find clear answers to the following:

1. If I write code in PHP or Python that uses GPL MySQL connectors for PHP or Python - which license applies to my code? That of PHP or Python, or GPL?
2. Can I run my PHP or Python code on a server and offer commercial services without the GPL?
3. Can I bundle my PHP code in an application and distribute it commercially without the GPL?
