How can i use Python and PHP together effectively
I know PHP and i am currently learning django Python. 

I am wondering the strengths and weaknesses of each language so that i can effectively use them together in order to program fater and more securly.

I know that PHP has much better(easier) string manipulation but python has better security. What are the other differences so that i know when to use the different languages?

I understand this is a 'very' broad question but i am hoping to hear your personal experience because that is something most books and tutorials wont talk about on this subject.
Any links, examples, theoris and facts are 'very' much appriciated!
