Re: substr passing null...

Well the $start parameter is required for substr(), so I don't see the deal here? But with now initalizers being added in the manual by Jakub its not much of a deal to use those values if you wanna use the default anyway. For example mysql_connect: http://www.php.net/mysql_connect But I do agree that in the end it would be easier to just be able to pass NULL, but it can just have a different meaning ;) > > -- > (c) Kenan Sulayman > Freelance Designer and Programmer > > Life's Live Poetry > > > 2009/1/28 Paul Biggar <paul.biggar@gmail.com> > >> On Wed, Jan 28, 2009 at 6:39 PM, Dan <dan@dancryer.com> wrote: >> >> >> >> You're assumption is wrong then, NULL isn't treated as not passing a >> >> value.
