How to cache the executed part of php code?

Question

PHP

Hello, I'm struggling with the problem of long site loading on WP, the bottleneck is in the loop (~ 1500 iterations) the register_taxonomy function is executed - it creates a PHP class object.
Is it possible to somehow cache this moment? Those. the result of executing a function or a complete loop?

Answer 1

You can't cache the loop, of course, but the result can be, for example, using serialize(), if there really is an object.
