Throwable

(PHP 7, PHP 8)

简介

PHP 7 里，Throwable 是能被 throw 语句抛出的最基本的接口（interface），包含了 Error 和 Exception。

Note:

PHP 类无法直接实现 （implement） Throwable 接口，而应当去继承 Exception。

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();

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:
