exception-with-context

Requirements

PHP >= 7.4.0

Installation

The preferred way to install this extension is through composer.

Either run

composer require beter/exception-with-context

or add

"beter/exception-with-context": "~1.0.0"  // put the actual version

to the require section of your composer.json.

Usage

Usage of the ExceptionWithContext:

use Beter\ExceptionWithContext\ExceptionWithContext;

$exceptionCode = 0;
$previousException = null;
$context = [
    'userIp' => '1.2.3.4',
    'userId' => 1,
    'request' => [
        'headers' => [ /* put headers data, for example */ ]
    ],
];

$e = new ExceptionWithContext('Action is not allowed for the user', $exceptionCode, $previousException, $context);

// or you may not to pass the context

$e = new ExceptionWithContext('Action is not allowed for the user', $exceptionCode, $previousException);

// or even skip $exceptionCode and $previousException

$e = new ExceptionWithContext('Action is not allowed for the user');

// or set context via setContext method call
$e = new ExceptionWithContext('Action is not allowed for the user');
$e->setContext($context);

// and get context back
var_dump($e->getContext());

You may create a chain of exceptions too:

use Beter\ExceptionWithContext\ExceptionWithContext;

try {
    do_smth();
} catch (\Throwable $catched) {
    $e = new ExceptionWithContext('Something went wrong', 0, $catched, ['key' => 'value']);
}

You may redefine your base exceptions and add context trait to them. They will behave the same way.

use Beter\ExceptionWithContext\ExceptionWithContextInterface;
use Beter\ExceptionWithContext\ExceptionWithContextTrait;

class CustomException extends \Exception implements ExceptionWithContextInterface
{
    use ExceptionWithContextTrait;

    public function __construct($message = "", $code = 0, Throwable $previous = null, array $context = [])
    {
        $this->context = $context;

        parent::__construct($message, $code, $previous);
    }
}

$e = new CustomException('Message text', 0, null, ['key' => 'value']);
$e->setContext(['newkey' => 'newvalue']);
var_dump($e->getContext());

Also, you may implement your own custom exceptions, you even don't need to use traits. Just implement Beter\Exception\ExceptionWithContextInterface.

Ideas for usage

• add context to log messages;
• protect from flooding exception message with placeholded values right into the message;
• pass more data to sentry/logentries/datadog/newrelic and so on.

You need to implement that support by yourself. There are only ideas.
