Anonymous functions pre PHP 5.3.0

Question

Is there an alternative to anonymous functions in PHP versions prior to 5.3.0?

Answer 1

There is create_function , but this is usually not recommended. If you use OOP, you better define a one-time private member for use with a callback.

Answer 2

Yes, create_function()

Answer 3

There are two options.

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

The second choice is to use create_function .
