I know a lot of people have their own comforts and styles when it comes to scripting and coding, but...
Some language documentations specifically state a naming convention that is considered best practice for their language, like Java specifying camelCase.
However, PHP's online documentation doesn't specify a naming convention (from what I've found, at least). Google searching this topic yields a lot of discussions akin to "What is generally accepted?" but I was wondering if people here know if there is an authoritative answer on the topic.
So, is it best practice to declare my variables...
What about functions?
