Re: echo count(false); == 1 ?!

I accept your argument as logical but look at the documentation: count() accepts 2 arguments. The first should be: "An array or countable object". From here I can tell you that 90% of your cases do not comply with the documentation so any argument pro or against us just speculation. Comply with the documentation and then file bugs ;) null is neither an array nor countable object. false also falls in that group! Use is_null for null values or compare with true/false for bool. If you don't know the possible range of your data the problem is not php ;) On Wed, Nov 27, 2013 at 7:58 PM, Daevid Vincent <daevid@daevid.com> wrote: > > > > -----Original Message----- > > From: Tsvetan Nikolov [mailto:live.webscore@gmail.com] > > Sent: Wednesday, November 27, 2013 10:15 AM > > To: Daevid Vincent > > Cc: PHP-General > > Subject: Re: [PHP] echo count(false); == 1 ?! > > > > Just think about it.
