An odd request.. I want to have optional function arguments that *aren't* defined unless values are explicitly passed. Sorta the equivalent of function foo($arg1_required, $arg2_optional=undef) if (isset($arg2_optional)) { print "explicit"; } else { print "not passed"; } } Something like this is possible in Perl through the 'undef' construct; is anything like this available in PHP? -- #ken P-)} Ken Coar, Sanagendamgagwedweinini http://Golux.Com/coar/ Author, developer, opinionist http://Apache-Server.Com/ "Millennium hand and shrimp!"
