1.2.102. Can’t Implement Throwable¶
Classes extending Throwable can’t be thrown, unless they also extend Exception. The same applies to interfaces that extends Throwable.
Although such code lints, PHP throws a Fatal error when executing or including it : Class fooThrowable cannot implement interface `Throwable <https://www.php.net/manual/en/class.`throwable <https://www.php.net/throwable>`_.php>`_, extend `Exception <https://www.php.net/exception>`_ or `Error <https://www.php.net/error>`_ instead.
<?php
// This is the way to go
class fooException extends \Exception { }
// This is not possible and a lot of work
class fooThrowable implements \throwable { }
?>
