objects as class variables

[codecowboy]

Can I use an object that I created such as Collection as a class variable for another object? If so, do I declare with a type specification like this: Collection $varname OR do I just declare like any other variable without a type specification like this: $varname.

Thank you

Yes; and variables work the same way. PHP is loosely typed: variables don't have types, their values do.

With the exception of PHP 5's type hinting... 😉
