The php.ini and php-fpm.ini file can be found in:

/opt/homebrew/etc/php/7.4/

php@7.4 is keg-only, which means it was not symlinked into /opt/homebrew,

because this is an alternate version of another formula.

If you need to have php@7.4 first in your PATH, run:

echo ‘export PATH=”/opt/homebrew/opt/php@7.4/bin:$PATH”’ >> ~/.zshrc

echo ‘export PATH=”/opt/homebrew/opt/php@7.4/sbin:$PATH”’ >> ~/.zshrc

For compilers to find php@7.4 you may need to set:

export LDFLAGS=”-L/opt/homebrew/opt/php@7.4/lib”

export CPPFLAGS=”-I/opt/homebrew/opt/php@7.4/include”
