Anonymous functions pre PHP 5.3.0

Is there an alternative to anonymous functions in versions of PHP previous to 开发者_StackOverflow社区5.3.0?

There is create_function but it generally isn't recommended. If you're using OOP, you'd be better off defining a one-off private member to use with a callback instead.

Yes, create_function()

There are two choices.

First is to create a function, inside a function. Unfortunately, it will pollute the global namespace.

The second choice is to use create_function.
