Are there helpful PHP naming conventions?
<p>I come from Java / Objective-C to PHP and find it <em>horrible</em>. I mean, PHP is nice, really. But when you look at a bunch of variables, you don't know: Is that an number? Is that an string? Or ist that even a fancy object that can perform actions when calling methods on it?</p>

<p>So I wonder if there are helpful re-usable naming conventions for variables to help figure out if something is an object, or if something is just a boring variable. I'd say if something is an object, i.e. an instance of a class, the first character must be BIG. But it's just a guess. Hope to read some tips from PHP pros :-)</p>
