Available Classes
ExceptionHandler Class
Josantonius\ExceptionHandler\ExceptionHandler
Sets a exception handler:
/** * Sets a exception handler. * * @param callable $callback Exception handler function. * @param string[] $runBeforeCallback Method names to call in the exception before run callback. * @param string[] $runAfterCallback Method names to call in the exception after run callback. * * @throws NotCallableException if the callback is not callable. * @throws WrongMethodNameException if the method names are not string or are empty. * * @see https://www.php.net/manual/en/functions.first_class_callable_syntax.php */ public function __construct( private callable $callback, private array $runBeforeCallback = [], private array $runAfterCallback = [] );
Exceptions Used
use Josantonius\ExceptionHandler\Exceptions\NotCallableException; use Josantonius\ExceptionHandler\Exceptions\WrongMethodNameException;
Usage
Examples of use for this library:
Sets basic exception handler
use Josantonius\ExceptionHandler\ExceptionHandler; function handler(\Throwable $exception) { /* do something */ } new ExceptionHandler( callback: handler(...) ); /** * If an exception is thrown, the following is executed: * * handler($exception) */
Sets methods to execute before calling the callback
use Josantonius\ExceptionHandler\ExceptionHandler; class FooException extends \Exception { public function context(): void { /* do something */ } } class Handler { public function exceptions(Throwable $exception): void { if ($exception instanceof FooException) { /* do something */ } } } new ExceptionHandler( callback: (new Handler())->exceptions(...), runBeforeCallback: ['context'] ); /** * If FooException() is thrown, the following is executed: * * FooException->context() * Handler->exceptions($exception) */
Sets methods to execute after calling the callback
use Josantonius\ExceptionHandler\ExceptionHandler; class FooException extends \Exception { public function report(): void { /* do something */ } public function render(): void { /* do something */ } } class Handler { public static function exceptions(Throwable $exception): void { if ($exception instanceof FooException) { /* do something */ } } } new ExceptionHandler( callback: Handler::exceptions(...), runAfterCallback: ['report', 'render'] ); /** * If FooException() is thrown, the following is executed: * * Handler::exceptions($exception) * FooException->report() * FooException->render() */
Sets methods to execute before and after calling the callback
use Josantonius\ExceptionHandler\ExceptionHandler; class FooException extends \Exception { public function context(): void { /* do something */ } public function report(): void { /* do something */ } public function render(): void { /* do something */ } } function exceptionHandler(Throwable $exception) { /* do something */ } new ExceptionHandler( callback: exceptionHandler(...), runBeforeCallback: ['context', 'logger'], runAfterCallback: ['report', 'render'] ); /** * If FooException() is thrown, the following is executed: * * FooException->context() * exceptionHandler($exception) * FooException->report() * FooException->render() * * FooException->logger() is ignored, does not exist in the exception. */
