[Nix-dev] Custom php.ini for cli calls

[Guillaume Maudoux (Layus)]

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 :-).

Layus.
