I have observed on my macOS 12.3 (21E230) for quite some time that Homebrew very often reinstalls the entire PHP package during an upgrade process and thus recompiles it as well.
> brew upgrade
(…)
==> No outdated dependents to upgrade!
==> Checking for dependents of upgraded formulae...
Disable this behaviour by setting HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK.
Hide these hints with HOMEBREW_NO_ENV_HINTS (see `man brew`).
==> Reinstalling 1 dependent with broken linkage from source:
php

I suspect some misconfiguration in this undesirable behavior, but can't see what exactly is wrong. I don't assume that PHP pushes near-weekly updates to the Homebrew formulas and therefore triggers the time-consuming recompilation for every tiny patch.
Analysis
The value of HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK is on the default setting. I don't suspect that the default value provokes this unnecessary recompilation. The man page describes this setting as: "Unless HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK is set, brew upgrade or brew reinstall will be run for outdated dependents and dependents with broken linkage, respectively". I don't see, why this should cause the recompiling: php is linked well.
> brew link php
Warning: Already linked: /usr/local/Cellar/php/8.1.4
To relink, run:
brew unlink php && brew link php
I uninstalled and deleted PHP in all existing versions - and then reinstalled.
I don't understand why brew info php shows an entry for version 8.1.3_1.reinstall. I fear that this is causing the problem.
> brew info php
