you can only assign 'basic' values (types) to vars in the class definition
(so no function calls) . e.g:
Yes, that's how I solved it just a minute ago, even though I didn't understand
why. Thanks for the enlightenment. :-)
BTW does PHP5 let you assign function values in the variable definition (like
C++)?
no. I believe the reasoning is that allowing you to define class vars with return
vals from functions opens the door to endless possibilities of weird side effects when
you load in the class. e.g:
class T
{
var $reconfigured = sometimesCompletelyReconfigureTheWebserver();
var $filesystemdeleted = recursiveDel('/');
}
you can imagine what kind of havoc the 2 imaginary functions may cause just by loading
the class T - I believe that the php devs want to avoid nightmares/confusion (especially for
'average' php coders) by not allowing this kind of syntax/[var-]definition. besides which there
are probably scope issues - imagine you want to pass a var to sometimesCompletelyReconfigureTheWebserver()
... what is the scope of the var, where does it come from?
