[COOK-2844] php.ini configuration overwrite

http://tickets.opscode.com/browse/COOK-2844

Hi to all,
When I try to overwrite configuration in php.ini with this cookbook all parameters are wrapped with quotes. A lot of configurations doesn't work.

In your opinion isn't better if you place directives without quotes and is the developer responsibility to add quotes in dedicated options?

    node["php"]["directives"]["short_tags"] = "On"
should be in php.ini

    short_tags = On

In case we need quotes

    node["php"]["directives"]["particular_string"] = "\"On\""

in php.ini

    particular_string = "On"
