note 50443 added to language.oop5.typehinting

Although type-hinting prevents null values from being passed, setting a default null value is not a parse error. However, calling the function with a null parameter, or calling it without the parameter (thus using the default value) will result in a fatal error: <?php function foo(MyClass $object = null) { // this is a valid function definition } $o = new MyClass(); foo($o); foo(null); // fatal error foo(); // fatal error ?> ---- Manual Page -- http://www.php.net/manual/en/language.oop5.typehinting.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+50443 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+50443&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+50443&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+50443&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+50443&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+50443&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+50443&report=yes Search -- http://master.php.net/manage/user-notes.php
