I will readily say PHP, main reason being that it is open-source, cheap to host online (a very important feature). But then in terms of strength, both are powerful languages.
Well, Since you asked between those 2, I'll boldly say PHP. Has more support, resources, easy learning curve and community backing.
PHP should be your best option....It's a widely-used open source for new beginners.. It can be easily embedded into HTML....
Quite correct @NUROYE1, that is enough reason. PHP rocks anytime!
That is a very good observation, I will see what I can do about that. Thanks for the great observation.
