Throwable

    (PHP 7, PHP 8)

    简介

    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。

    接口摘要

    interface Throwable extends Stringable {
    /* 方法 */
    public getMessage(): string
    public getCode(): int
    public getFile(): string
    public getLine(): int
    public getTrace(): array
    public getTraceAsString(): string
    public getPrevious(): ?Throwable
    public __toString(): string
    /* 继承的方法 */
    public Stringable::__toString(): string
    }

    更新日志

    版本 说明
    8.0.0 现在 Throwable 实现了 Stringable。

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

    You can find this script here:
    https://gist.github.com/mlocati/249f07b074a0de339d4d1ca980848e6a

    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();
