PHP 8.1.0 RC 4 available for testing

Throwable

(PHP 7, PHP 8)

Einführung

Throwable ist das zugrundeliegende Interface aller Objekte, die mittels des throw-Statements geworfen werden können, inklusive Error und Exception.

Hinweis:

PHP-Klassen können das Interface Throwable nicht direkt implementieren und müssen stattdessen von Exception abgeleitet werden.

Interface-Übersicht

interface Throwable {
/* Methoden */
public getMessage(): string
public getCode(): int
public getFile(): string
public getLine(): int
public getTrace(): array
public getTraceAsString(): string
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:
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();
