(PHP 7, PHP 8)


Throwable is the base interface for any object that can be thrown via a throw statement, including Error and Exception.


PHP classes cannot implement the Throwable interface directly, and must instead extend Exception.

Interface synopsis

interface Throwable extends Stringable {
/* Methods */
public getMessage(): string
public getCode(): int
public getFile(): string
public getLine(): int
public getTrace(): array
public __toString(): string
/* Inherited methods */


Version Description
8.0.0 Throwable implements Stringable now.

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();
