Re: Fwd: Re: [PHP-PEAR] PEAR::isError()

It doesn't make sense. But it's very practical syntax-wise, right now it is impossible to pass a value such as "true" or "array(1,2,3)" to a function that wants a reference. But as Zeev says, maybe the right solution in all cases then is to "de-reference :-)" the parameter. - Stig Andi Gutmans wrote: > > Why does it make sense to send constants by reference? > > Andi > > At 03:03 PM 12/4/00 -0500, Chuck Hagenbuch wrote: > >In case core people interested in this aren't on the pear list... > > > >----- Forwarded message from "Stig S.
