Description:
------------
on a fresh install of httpd/apache : 

brew install httpd php@7.2


pecl install grpc protobuf xdebug

extensions will be included at the top of the php.ini file as exension
and in the XDebugSection for all 3 pacakges while it's valid only for the XDEbug.

I've added an XDebug section before running the installation

Running php on command line then produce this :

$ php
/usr/local/lib/php/pecl/20170718/grpc.so doesn't appear to be a valid Zend extension
/usr/local/lib/php/pecl/20170718/protobuf.so doesn't appear to be a valid Zend extension

normal extension are also added multiple time 


Test script:
---------------
brew install httpd php@7.2
pecl install grpc protobuf xdebug

php
