Php development server is excellent thing for quick development. But seems not very clear how to setup custom php parameters such as
upload_max_filesize. Putting
php.ini into main folder does not work for me, and even setting with
ini_set failed. Desperatly I desided to read manual. Yes, sometimes it is worth do so ;>. But
/usr/local/Cellar/php/7.4.8/bin/php -S localhost:8081 -d upload_max_filesize=12M
And remember phpinfo() function is your friend.
alternatively you can always set global value in the
vi /usr/local/etc/php/7.4/php.ini file.
