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 extends Stringable {
/* Methoden */
public getMessage (): string
public getCode (): int
public getFile (): string
public getLine (): int
public getTrace (): array
public getPrevious (): ? Throwable
public __toString (): string
/* Geerbte Methoden */
}

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();
