Sameer Borate's Blog:
Anonymous functions in PHP
June 07, 2010 @ 12:42:33

On his blog today Sameer Borate has a new post talking about anonymous functions (closures, lambdas) in PHP and includes plenty of examples of how to use them.

Anonymous functions are common in various modern languages, Ruby and Javascript being the popular one. But until version 5.3 PHP lacked true anonymous functions. Although newbie programmers are hard-pressed to find a suitable application for anonymous functions, they are indispensable if you do a lot of OOP, and can provide some elegant solutions to some particular problems.

He starts with a look at variable functions both in procedural code an object-oriented then moves to the anonymous/lambda function examples (with some nexting involved) and a few uses for closures.
