/**
 * Monolog handler for Google Chrome extension &quot;PHP Console&quot;
 *
 * Display PHP error/debug log messages in Google Chrome console and notification popups, executes PHP code remotely
 *
 * Usage:
 * 1. Install Google Chrome extension [now dead and removed from the chrome store]
 * 2. See overview https://github.com/barbushin/php-console#overview
 * 3. Install PHP Console library https://github.com/barbushin/php-console#installation
 * 4. Example (result will looks like http://i.hizliresim.com/vg3Pz4.png)
 *
 *      $logger = new \Monolog\Logger('all', array(new \Monolog\Handler\PHPConsoleHandler()));
 *      \Monolog\ErrorHandler::register($logger);
 *      echo $undefinedVar;
 *      $logger-&gt;debug('SELECT * FROM users', array('db', 'time' =&gt; 0.012));
 *      PC::debug($_SERVER); // PHP Console debugger for any type of vars
 *
 * @author Sergey Barbushin https://www.linkedin.com/in/barbushin
 *
 * @phpstan-import-type Record from \Monolog\Logger
 * @deprecated Since 2.8.0 and 3.2.0, PHPConsole is abandoned and thus we will drop this handler in Monolog 4
