如何在php中缓存闭包

Question

I want to cache an array which has also closures.

I've tried with:

• serialize() - can't serialize closures
• json_encode() - replaces closure with empty value
• base64_encode() - doesn't accept arrays

What else to do for caching array containing also closures ?

Answer 1

Closures in PHP can not be serialized "from the box" hence array with closures too. You can only use 3rd party ways/libraries to reach this. Discussed here: Serializing anonymous functions in php
