PHP type cast (unset)
I would love to see a use case in php for type casting to (unset)
Update:2017-07-13 This seems to confirm there is no use for (unset) since it is slated for deprecation in 7.2 🙂
https://wiki.php.net/rfc/deprecations_php_7_2#unset_cast
php > $var = "hello world";
php > var_export((unset) $var);
NULL
php > var_export($var);
'hello world'
