    Update: after trying to downgrade from 8.2 to 7.4, php -v threw the following error:

    dyld[4170]: Library not loaded: /opt/homebrew/opt/icu4c/lib/libicuio.71.dylib

zsh: abort      php -v

    To solve, had to install icu4c package @ 71.1, remove 73, and symlink the default location to 71.1:

    Install package @ version:

    brew tap-new $USER/local-icu4c
brew tap homebrew/core
brew extract --version=71.1 icu4c $USER/local-icu4c
brew install icu4c@71.1

    As per it's instructions, the following done too - don't think this helped, should probably still look at undoing this;

    export LDFLAGS="-L/opt/homebrew/opt/icu4c@71.1/lib"
export CPPFLAGS="-I/opt/homebrew/opt/icu4c@71.1/include"

    Uninstall the regular one and symlink;

    brew uninstall --ignore-dependencies icu4c # regular uninstall was failing as it's a required dependency
cd /opt/homebrew/opt
ln -s icu4c@71.1 icu4c
