This thing is not called "ifsetor". From the commit message: ?: operator [DOC] "expr1 ?: expr1" is a shortcut for: "expr1 ? expr1 : expr2" as exists in gcc and discussed some time back. Note that this is not an implementation ifsetor($var, default). While ifsetor would not generate any message for non existing variables or array indices the ternary shortcut does. Also the ternary shortcut does a boolean evaluation rather then checking for isset(). That way ther ternary shortcut can work on any expression while ifsetor can only work on variables. Also to be silent one has do do: "@$expr1 ?: $expr2". I didn't check the docs, if it is documented as "ifsetor" there that's wrong. For reasons why there is no "ifsetor" but this operator please check the archives. johannes -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
