​I would recommend being careful about that experiment since there is a
high probability that Ben uses php-fpm (it's actually the recommended way
compared to the old FastCGI + php-cgi and the related issues).
First Ben​

​should ensure that php-cgi and php-fpm shares the exact same ini
configuration. That's a common caveat... :o)

​That's the best way of proceeding since it uses the exact environment PHP
will be using for production-ready code. Wireshark may be used to read pcap
dumps with a nice graphical presentation.​
