The Truth About Lambdas and Closures in PHP

One of PHP5.3's terrific features is the ability to use lambdas, a feature which will surely relegate PHP 5.0's lambda-style in the guise of create_function() to the dust-bin of cyberspace. This presentation will focus on what exactly lambdas are as well as the difference between a lambda and a closure, or whether there is any given their implementation in PHP. In addition, we'll have a look at improvements pertaining to closures in the upcoming PHP 5.4. Far greater emphasis is on live code demonstrations as well as in-depth discussion about the code.
