To enable PHP in Apache add the following to httpd.conf and restart Apache:
LoadModule php_module /opt/homebrew/opt/php/lib/httpd/modules/libphp.so
<FilesMatch \.php$>
SetHandler application/x-httpd-php
</FilesMatch>
Finally, check DirectoryIndex includes index.php
DirectoryIndex index.php index.html
The php.ini and php-fpm.ini file can be found in:
/opt/homebrew/etc/php/8.0/
To restart shivammathur/php/php after an upgrade:
brew services restart shivammathur/php/php
Or, if you don't want/need a background service you can just run:
/opt/homebrew/opt/php/sbin/php-fpm --nodaemonize

Also --build-from-source didn't work.
Are you willing to submit a PR?
I think the formular looks correct. Not sure why this error happens for me.
Workaround
# php 8
ln -s /opt/homebrew/include/pcre2.h /opt/homebrew/opt/php@8.0/include/php/ext/pcre/pcre2.h
# php 7.4
ln -s /opt/homebrew/include/pcre2.h /opt/homebrew/opt/php@7.4/include/php/ext/pcre/pcre2.h
# php 7.2
ln -s /opt/homebrew/include/pcre2.h /opt/homebrew/opt/php@7.2/include/php/ext/pcre/pcre2.hNot sure why the pcre2.h is not there or why it can not be found?
I would recommend using shivammathur/extensions tap for installing extensions.
But if you want to use pecl, you will have to copy the pcre2.h to php's include directory. This workaround is required since the macOS sdk changes in macOS Catalina.
pcre2_h="$(find "$(brew --cellar pcre2)" -name "pcre2.h")"
cp -f "$pcre2_h" "$(brew --cellar php)"/*/include/php/ext/pcreBut you will have to do this after every PHP release or if you switch PHP version.
@shivammathur Thx for the fast response. I will have a look also at the extension brew tap.
