The DevTheWeb.net blog is back again with the second installment of "Things You Probably Didn't Know About PHP" - some lesser known facts about the popular web language (part one is here).
Some of the things on his list this time include:
- Using the type matching equality operators (like "===" versus just "==")
- Returning multiple values by reference
- Chaining method calls
- Returning the value of print_r as a string
- Using the mysqli functions instead of just mysql
