/**
 * A generic ErrorHandler for the PHP engine.
 *
 * Provides five bit fields that control how errors are handled:
 * - thrownErrors: errors thrown as \ErrorException
 * - loggedErrors: logged errors, when not @-silenced
 * - scopedErrors: errors thrown or logged with their local context
 * - tracedErrors: errors logged with their stack trace
 * - screamedErrors: never @-silenced errors
 *
 * Each error level can be logged by a dedicated PSR-3 logger object.
 * Screaming only applies to logging.
 * Throwing takes precedence over logging.
 * Uncaught exceptions are logged as E_ERROR.
 * E_DEPRECATED and E_USER_DEPRECATED levels never throw.
 * E_RECOVERABLE_ERROR and E_USER_ERROR levels always throw.
 * Non catchable errors that can be detected at shutdown time are logged when the scream bit field allows so.
 * As errors have a performance cost, repeated errors are all logged, so that the developer
 * can see them and weight them as more important to fix than others of the same level.

Debug Component
===============

**CAUTION**: this component is deprecated since Symfony 4.4. Instead, use the
[ErrorHandler component](https://github.com/symfony/symfony/tree/master/src/Symfony/Component/ErrorHandler).

-----

The Debug component provides tools to ease debugging PHP code.

Getting Started
---------------

```
$ composer require symfony/debug
```

```php
use Symfony\Component\Debug\Debug;

Debug::enable();
```

Resources
---------

 * [Contributing](https://symfony.com/doc/current/contributing/index.html)
 * [Report issues](https://github.com/symfony/symfony/issues) and
   [send Pull Requests](https://github.com/symfony/symfony/pulls)
   in the [main Symfony repository](https://github.com/symfony/symfony)
