Dynamic data? Need some tips, please

Ok, I’m looking into learning about databasing and dynamic content for websites. I’ve talked to a few people, and all of them told me to go PHP + MySQL or Coldfusion. I have also searched online, but what came up wasn’t what I’m looking for.

Basically, should I dive into PHP/MySQL or Coldfusion? Do they have pros / cons? What would be more efficient for my time? Thanks, Sorry to be so broad but it’s the only way I can explain my question.

Hope some people can help. :worried:
