#19252 [Opn]: function only accepts scalars or constants as default values

ID: 19252 User updated by: jc at mega-bucks dot co dot jp Reported By: jc at mega-bucks dot co dot jp Status: Open Bug Type: Documentation problem Operating System: all PHP Version: 4.3.0 New Comment: I agree that is *is* documented, even if a bit hidden. I am happy if the documentation is left as is or changed to this: "The default value must be a constant expression, not (for example) a variable, class member, <NEW ADDITION> or function call </NEW ADDITION>. Thanks.

Can you give a URL to the section of the documentation you're asking to be updated? ------------------------------------------------------------------------ [2002-09-05 11:09:23] jc at mega-bucks dot co dot jp Could you add to the docs in the section on functions and default argument values that default values can only be scalers or constants? these won't work: 1- function a ($b = $val) {} 2- function b ($a = another_function()) {} This link offers some workarounds, eventhough it would be really nice to be able to do #2, don't you think ;) http://marc.theaimsgroup.com/?l=php-general&m=91877248424055& ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19252&edit=1
