Those still trying to get a handle on anonymous functions, lambdas and closures in the recently released 5.3 version of PHP might want to take a look at this new tutorial from the Recess blog. It's the first part of their "Functional PHP 5.3" series.

They explain the differences between closures and lambda functions (hint: not much) and give code examples for both them and closures.
