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 ErrorException

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

Throwable {
/* 方法 */
abstract public getMessage ( ) : string
abstract public getCode ( ) : int
abstract public getFile ( ) : string
abstract public getLine ( ) : int
abstract public getTrace ( ) : array
abstract public getTraceAsString ( ) : string
abstract public getPrevious ( ) : Throwable
abstract public __toString ( ) : string
}

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();
