This extension is very useful in the development stage of project. It helps you to get info about PHP environment, application, queries logs, benchmarking with a simple little toolbar at the top of the page.

It is a recreated Symfony's developer toolbar. First idea and very first implementation was my, but this version mostly implemented by Eduard Kuleshov.

• Yii 1.0 or above (it's not tested with Yii 2.x compatibility, check it by yourself, please)

• Extract the release file under protected/extensions

##Usage

main.php configuration file update:

// ...
// autoloading model and component classes
'import'=>array(
  'application.models.*',
  'application.components.*',
  'application.extensions.yiidebugtb.*', // our extension
),
// ...
'log'=>array(
  'class'=>'CLogRouter',
    'routes'=>array(
      array(
        'class'=>'CFileLogRoute',
        'levels'=>'error, warning, trace',
      ),
      // toolbar configuration (see available options below)
      array(
        'class'=>'XWebDebugRouter',
        'config'=>'alignLeft, opaque, runInDebug, fixedPos, collapsed, yamlStyle, dbProfiling',
        'levels'=>'error, warning, trace, profile, info',
        'allowedIPs'=>array('127.0.0.1','::1','192.168.1.54','192\.168\.1[0-5]\.[0-9]{3}'),
      ),
    ),
),
// ...

###Options reference

• 'alignLeft' - debug toolbar will be aligned to the top left corner of browser window;
• 'opaque' - makes the debug toolbar almost invisible when it’s minimized;
• 'runInDebug' - show the debug toolbar only if Yii application running in DEBUG MODE (see index.php for details);
• 'fixedPos' - makes the debug toolbar sticky with browser window, not document!;
• 'collapsed' - show the debug toolbar minimized by default;
• 'yamlStyle' - show configuration report in Yaml or PHP-array style.
• 'dbProfiling' - enable profiling of DB queries and param logging. (see CDbConnection::$enableProfiling and CDbConnection::$enableParamLogging)

Also there is an additional security feature you may need - 'allowedIPs' option. This option holds the array of IP addresses of all machines you need to use in development cycle. So if you forget to remove YII_DEBUG from bootstrap file for the production stage, your client don't see the toolbar anyway.
