note 80379 added to language.functions

Suppose we have a method function appendChildNode( AST $aNewChild ) { .... } which is defined inside of the class AST. If I pass a null value, I get this error message: >> Catchable fatal error: Argument 1 passed to AST::appendChildNode() must be an instance of AST, null given, called in /Applications/MAMP/htdocs/compile/includes/CParser.inc.php(517) : eval()'d code on line 1 and defined in /Applications/MAMP/htdocs/compile/includes/AST.inc.php on line 43 <<< Can't we pass null for a class-typed argument? ---- Server IP: 212.124.37.9 Probable Submitter: 77.186.136.74 ---- Manual Page -- http://www.php.net/manual/en/language.functions.php Edit -- https://master.php.net/note/edit/80379 Del: integrated -- https://master.php.net/note/delete/80379/integrated Del: useless -- https://master.php.net/note/delete/80379/useless Del: bad code -- https://master.php.net/note/delete/80379/bad+code Del: spam -- https://master.php.net/note/delete/80379/spam Del: non-english -- https://master.php.net/note/delete/80379/non-english Del: in docs -- https://master.php.net/note/delete/80379/in+docs Del: other reasons-- https://master.php.net/note/delete/80379 Reject -- https://master.php.net/note/reject/80379 Search -- https://master.php.net/manage/user-notes.php
