In this specific case we could modify the behaviour of the value of the ini setting to make this configurable. As it stands, the value is treated as a bit mask with three bits that have meaning, we could make the fourth bit mean "issue an error on every function call" when set, if it's clear then issue a warning only once during rinit when the value is non-zero. I realise this is a slightly horrible solution, just throwing it out there as a possibility. I'd argue that it's not really any *more* horrible than the feature in general, though. > > > Regards, > -- > Rowan Collins > [IMSoP] > > -- > PHP Internals - PHP Runtime Development Mailing List > To unsubscribe, visit: http://www.php.net/unsub.php > >
