Question

I was reading about Closure interface here:

http://www.php.net/class.closure

Then I googled it and couldn’t find good examples of usage so I decided to post it here. Also there is no example on php.net site as well. Can anyone (probably experienced PHP dev) describe me how and where can I use it to take advantage on it?

Answer 1

The place that immediately sprungs to mind is the various array_* functions, such as array_walk(). They are already often used with create_function(); the new closure notation makes this existing structure just that little bit more elegant.

I’m sure there will be more.
