ini_get_all() - doesn't get all !

[lionpete]

How come when I use ini_get() or ini_get_all() I don't get all the diretives defined in my php.ini?

Most are returned, but not all!
For example the sybase.interface_file directive is not returned. also 'sybct.hostname' is present but NULL in the return from ini_get_all() but is not defined in my php.ini.

I am trying to get PHP talking to a remote sybase server, and failing with miserable regularity
😕

I am using an apache 2.0.48 server on Windows XP with php-4.3.6

Thanks in advance to you wonderful people
