note 23498 added to functions.arguments

Concerning default values for arguments passed by reference: I often use that trick: func($ref=$defaultValue) { $ref = "new value"; } func(&$var); print($var) // echo "new value" Setting $defaultValue to null enables you to write functions with optional arguments which, if given, are to be modified. -- http://www.php.net/manual/en/functions.arguments.php http://master.php.net/manage/user-notes.php?action=edit+23498 http://master.php.net/manage/user-notes.php?action=delete+23498 http://master.php.net/manage/user-notes.php?action=reject+23498
