The difference between get_cfg_var() and ini_get() is that the former
returns whatever is in php.ini while the latter returns the runtime
settings. Say you stick the following into php.ini:
[tomkat]
tomcruise.secret = "He's gay!"
get_cfg_var() will happily return the text while ini_get() would not,
as it's not configurable option belonging to any extension. Or, in
another word, ini_get() will only return items that are defined in the
source code.
