Yep: $ sapi/cli/php -r '$x = NULL; $y = NULL; $z = 3; var_dump($x ?? $y ?? $z);' int(3) $ sapi/cli/php -r '$x = ["yarr" => "meaningful_value"]; var_dump($x["aharr"] ?? $x["waharr"] ?? $x["yarr"]);' string(16) "meaningful_value" -- Andrea Faulds http://ajf.me/ -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
