Updating PHP-closures tag

manpreet Best Answer 2 years ago

There is a php-closures tag although there is no description of this tag so I didn't find it until I searched through the tags DB.

I did some research to understand closures, and I came across a good post to explain why this extra tag is needed.

Quote from PHP.net user:

This caused me some confusion a while back when I was still learning what closures were and how to use them, but what is referred to as a closure in PHP isn't the same thing as what they call closures in other languages (E.G. JavaScript).

In JavaScript, a closure can be thought of as a scope, when you define a function, it silently inherits the scope it's defined in, which is called its closure, and it retains that no matter where it's used. It's possible for multiple functions to share the same closure, and they can have access to multiple closures as long as they are within their accessible scope.

In PHP, a closure is a callable class, to which you've bound your parameters manually.

It's a slight distinction but one I feel bears mentioning.

So can I please get some help so I can update it?

I am currently struggling to really define it for the tag. I am happy to post the tag update myself obviously.
