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:

PHP - Manual: Throwable
2024-12-23
(PHP 7, PHP 8)
Throwable 是能被 throw
语句抛出的最基本的接口(interface),包含了
Error 和 Exception 。
注意:
PHP 类无法直接实现 (implement) Throwable 接口,而应当去继承 Exception。
版本 | 说明 |
---|---|
8.0.0 | 现在 Throwable 实现了 Stringable。 |
