I'm a 5 years Python programmer, but shortly I'll be also working with PHP. Could you recommend me some readings to getting in touch with this language having in mind my Python skills?
If you are familiar with MVC start learning from Zend Framework I think it will be easier for you to understand php, right php developing this way with a right leg start. 
Object oriented business logics are same in any language. 
I really want to get into python so we can exchange knowledge ;)
PHP for Python programmers?
