That being said, you can also start php with the right arguments.
It seems to me that php does not read any configuration file from the
derivation when it starts.
$ php --ini
Configuration File (php.ini) Path:
/nix/store/hr30lz6ziqinsbi525fm9han3lr9nsmj-php-5.6.16/etc
Loaded Configuration File: (none)
Scan for additional .ini files in: /etc
Additional .ini files parsed: (none)
so you probably need to put your own php.ini file in /etc or call php -c
<custom_ini_file>
Nothing to do with the derivation :-).
