1.2.861. Null On New¶
Until PHP 7, some classes instantiation could yield null, instead of throwing an exception.
After issuing a ‘new’ with those classes, it was important to check if the returned object were null or not. No exception were thrown. This inconsistency has been cleaned in PHP 7 : see See Internal Constructor Behavior
<?php
// Example extracted from the wiki below
$mf = new MessageFormatter('en_US', '{this was made intentionally incorrect}');
if ($mf === null) {
echo 'Surprise!';
}
?>
See also PHP RFC: Constructor behaviour of internal classes.
1.2.861.1. Suggestions¶
Remove the check on null after a new instantiation
