By the way, the original article was published in 2017 and compared PHP 5.6 instead of 7 using an inappropriate benchmarking method, so I don't think it's worth reading. https://qiita.com/kapitan/items/47d89449f23bc7f7c9bb

PHPを少しでも速く動かしたい - Qiita

色々調べると先人方が調べてくれています。とはいえ、情報が散らばってるので個人的にまとめたかったのと現状どのくらい効果あるのか知りたいので遊んでみる。どのくらい効果あるのか検証は100回〜1000回計測での平均 PHPは5.6.30 VMで動かしてるからちょっと遅い^^...

These are certainly interesting, but from the perspective of solving bottlenecks, it's pointless to even consider them, and they don't seem to be hotspots in the PHP interpreter.

I saw a user post claiming there was a pattern that was faster than the native is_bool() (ZEND_TYPE_CHECK), so I put a comment about a quick benchmark in a Gist. https://gist.github.com/zonuexe/008fdbdff728a0ec3a45b0c5f6788c22

Recursive calls are a poor practice for PHP, but it does remove one of the justifications for the existence of references.

I wrote about the Closure::getCurrent() method, which was added to the master branch of php without an RFC to allow anonymous recursion.
