1.2.1332. Use NullSafe Operator¶
The nullsafe operator
?->is an alternative to the object operator->. It silently fails the whole expression if a null is used for object.
<?php
$o = null;
// PHP 8.0 Failsafe : $r = null;
$r = $o->method();
// PHP 7.4- : Call to a member function method() on null
$r = $o->method();
?>
