Throwable

(PHP 7)

Вступ

Throwable is the base interface for any object that can be thrown via a throw statement in PHP 7, including Error and Exception.

Зауваження:
PHP classes cannot implement the Throwable interface directly, and must instead extend Exception.

I wrote a simple script that prints out the Throwable and Exception tree for every PHP version.

You can find this script here:

And its output is here:

try {
// Code that may throw an Exception or Error.
} catch (Throwable $t) {
// Executed only in PHP 7, will not match in PHP 5.x
} catch (Exception $e) {
// Executed only in PHP 5.x, will not be reached in PHP 7
}

interface MyPackageThrowable extends Throwable {}

class MyPackageException extends Exception implements MyPackageThrowable {}

throw new MyPackageException();
