note 126395 added to language.operators.comparison

Not mentioned in this document regarding the Null Coalescing Operator is that you can use is as an assigning operator (??=) and works nicely. <?php echo $test; // PHP Warning: Undefined variable $test echo $test ?? 'foo'; // prints 'foo' without error // $test remains undefined, echo $test still throw a PHP warning $test ??= 'bar'; // $test is undefined therefore equals NULL // no error, $test is now set to 'bar' echo $test ?? 'baz'; // $test is no longer undefined/NULL, prints 'bar' without error $test ??= 'baz'; // $test is no longer undefined/NULL, $test is not changed echo $test; // prints 'bar' ?> ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.242 (proxied: 89.238.150.174) ---- Manual Page -- https://php.net/manual/en/language.operators.comparison.php Edit -- https://main.php.net/note/edit/126395 Del: integrated -- https://main.php.net/note/delete/126395/integrated Del: useless -- https://main.php.net/note/delete/126395/useless Del: bad code -- https://main.php.net/note/delete/126395/bad+code Del: spam -- https://main.php.net/note/delete/126395/spam Del: non-english -- https://main.php.net/note/delete/126395/non-english Del: in docs -- https://main.php.net/note/delete/126395/in+docs Del: other reasons-- https://main.php.net/note/delete/126395 Reject -- https://main.php.net/note/reject/126395 Search -- https://main.php.net/manage/user-notes.php
