So reading all posts on this subject, the proposal would be:
1) Allow null typehints
publicÂfunctionÂCompare([BaseClass]Â$objA,Â$cmpFunc);
Ex: Compare(null, 'func1');
2) Don't allow null typehints
publicÂfunctionÂCompare(BaseClassÂ$objA,Â$cmpFunc);
Ex: Compare(new BaseClass(), 'func1');
3) Optional argument (with typehint)
publicÂfunctionÂCompare($cmpFunc,ÂBaseClassÂ$objA=null);
Ex: Compare('func1');
Am I right ? Is it possible to implement all three syntaxes ?
IMH it would satisfy everybody's needs.
