Bug->Doc #52605 [Opn]: get_class(NULL) returns class name when called insid member function of a class

Edit report at http://bugs.php.net/bug.php?id=52605&edit=1 ID: 52605 Updated by: cataphract@php.net Reported by: rahul dot pache at gmail dot com Summary: get_class(NULL) returns class name when called insid member function of a class Status: Open -Type: Bug +Type: Documentation Problem Package: *General Issues Operating System: windows 7 PHP Version: 5.3.3 Block user comment: N New Comment: This is actually a documentation problem. The convention is to give internal functions that have optional arguments a default value and have them behave the same way when the default value is given and when the argument's not passed at all. In PHP 5.2, you could not pass an argument to get_class and have it have the same behavior as when nothing is passed. This was fixed in PHP 5.3 by making "NULL" the default argument value.
