Previous Comments: ------------------------------------------------------------------------ [2016-08-28 18:42:20] dailywatchdeal at gmail dot com Description: ------------ According to the docs, the ?? operator checks if the 1st operand exists and is not null. In other words, it's equivalent to isset. When used to check if a SimpleXMLElement node exists, it doesn't work. Test script: --------------- <?php $xml = new SimpleXMLElement('<root><elem>Text</elem></root>'); echo 'elem2 is: ' . ($xml->elem2 ?? 'backup string'); echo 'elem2 is: ' . (isset($xml->elem2) ? $xml->elem2 : 'backup string'); Expected result: ---------------- elem2 is: backup string elem2 is: backup string Actual result: -------------- elem2 is: elem2 is: backup string ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72957&edit=1
