how they are aligned in memory doesn't make them different in what they are. Either way you still have a 2 dimential matrix. > > and in PHP it can get even more confusing with its non strict typing, and > un-fixed size arrays etc... Some would argue this. PHP makes it easier for the programmer, so he doesn't have to worry about type differences, memory allocation and lower level access. The programmer just needs to assign a variable and poof... it is created. > > Andrew > ----- Original Message ----- > From: "Curt Zirzow" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Saturday, August 02, 2003 11:06 PM > Subject: Re: [PHP] Pushing array onto array > > > > * Thus wrote Andrew Brampton ([EMAIL PROTECTED]): > > > > > > It works exactly how it should...
