composer require josantonius/error-handler --prefer-source

You can also clone the complete repository with Git:

git clone https://github.com/josantonius/php-error-handler.git

Available Classes

ErrorException Class

Josantonius\ErrorHandler\ErrorException Extends ErrorException

Gets error file:

public function getFile(): string;

Gets error level:

public function getLevel(): int;

Gets error file line:

public function getLine(): int;

Gets error message:

public function getMessage(): string;

Gets error name:

public function getName(): string;

ErrorHandled Class

Josantonius\ErrorHandler\ErrorHandled

Gets error file:

public function getFile(): string;

Gets error level:

public function getLevel(): int;

Gets error file line:

public function getLine(): int;

Gets error message:

public function getMessage(): string;

Gets error name:

public function getName(): string;

ErrorHandler Class

Josantonius\ErrorHandler\ErrorHandler

Convert errors to exceptions:

/**
 * The errors will be thrown from the ErrorException instance.
 * 
 * @param int[] $errorLevel Define the specific error levels that will become exceptions.
 * 
 * @throws WrongErrorLevelException if error level is not valid.
 * 
 * @see https://www.php.net/manual/en/errorfunc.constants.php to view available error levels.
 */
public function convertToExceptions(int ...$errorLevel): ErrorHandler;

Convert errors to exceptions except for some of them:

/**
 * The errors will be thrown from the ErrorException instance.
 * 
 * @param int[] $errorLevel Define the specific error levels that will become exceptions.
 * 
 * @throws WrongErrorLevelException if error level is not valid.
 * 
 * @see https://www.php.net/manual/en/errorfunc.constants.php to view available error levels.
 */
public function convertToExceptionsExcept(int ...$errorLevel): ErrorHandler;

Register error handler function:

/**
 * The error handler will receive the ErrorHandled object.
 * 
 * @see https://www.php.net/manual/en/functions.first_class_callable_syntax.php
 */
public function register(callable $callback): ErrorHandler;

Use error reporting to determine which errors are handled:

/**
 * If the setting value in error_reporting() is used to determine which errors are handled.
 *
 * If this method is not used, all errors will be sent to the handler.
 *
 * @see https://www.php.net/manual/en/function.error-reporting.php
 */
public function useErrorReportingLevel(): ErrorHandler;

Exceptions Used

use Josantonius\ErrorHandler\Exceptions\WrongErrorLevelException;

Usage

Examples of use for this library:

Convert all errors to exceptions

use Josantonius\ErrorHandler\ErrorHandler;

$errorHandler = new ErrorHandler();

$errorHandler->convertToExceptions();

// All errors will be converted to exceptions.

Convert certain errors to exceptions

use Josantonius\ErrorHandler\ErrorHandler;

$errorHandler = new ErrorHandler();

$errorHandler->convertToExceptions(E_USER_ERROR, E_USER_WARNING);

// Only E_USER_ERROR and E_USER_WARNING will be converted to exceptions.

Convert all errors to exceptions except for some of them

use Josantonius\ErrorHandler\ErrorHandler;

$errorHandler = new ErrorHandler();

$errorHandler->convertToExceptionsExcept(E_USER_DEPRECATED, E_USER_NOTICE);

// All errors except E_USER_DEPRECATED and E_USER_NOTICE will be converted to exceptions.

Convert to exceptions using error reporting level

use Josantonius\ErrorHandler\ErrorHandler;

error_reporting(E_USER_ERROR);

$errorHandler = new ErrorHandler();

$errorHandler->convertToExceptions()->useErrorReportingLevel();

// Only E_USER_ERROR will be converted to exception.

Convert to exceptions and use an exception handler

use ErrorException;
use Josantonius\ErrorHandler\ErrorHandler;

set_exception_handler(function (ErrorException $exception) {
    var_dump([
        'level'   => $exception->getLevel(),
        'message' => $exception->getMessage(),
        'file'    => $exception->getFile(),
        'line'    => $exception->getLine(),
        'name'    => $exception->getName(),
    ]);
});

$errorHandler = new ErrorHandler();

$errorHandler->convertToExceptions();

// All errors will be converted to exceptions.

Register an error handler function

use Josantonius\ErrorHandler\ErrorHandled;
use Josantonius\ErrorHandler\ErrorHandler;

function handler(Errorhandled $errorHandled): void {
    var_dump([
        'level'   => $errorHandled->getLevel(),
        'message' => $errorHandled->getMessage(),
        'file'    => $errorHandled->getFile(),
        'line'    => $errorHandled->getLine(),
        'name'    => $errorHandled->getName(),
    ]);
 }

$errorHandler = new ErrorHandler();

$errorHandler->register(
    callback: handler(...)
);

// All errors will be converted to exceptions.

Register error handler function and convert to exceptions

use Josantonius\ErrorHandler\ErrorHandled;
use Josantonius\ErrorHandler\ErrorHandler;

class Handler {
    public static function errors(Errorhandled $exception): void { /* do something */ }
}

$errorHandler = new ErrorHandler();

$errorHandler->register(
    callback: Handler::errors(...)
)->convertToExceptions();

// The error will be sent to the error handler and then throw the exception.

Register error handler function, convert to exceptions and use error reporting level

error_reporting(E_USER_ERROR);

class Handler {
    public function errors(Errorhandled $exception): void { /* do something */ }
}

$handler = new Handler();

$errorHandled->register(
    callback: $handler->errors(...),
)->convertToExceptions()->useErrorReportingLevel();

// Only E_USER_ERROR will be passed to the handler and converted to exception.
