ZFDebug - a debug bar for Zend Framework

ZFDebug is a plugin for the Zend Framework for PHP5, providing useful debug information displayed in a small bar at the bottom of every page.

Time spent, memory usage and number of database queries are presented at a glance. Additionally, included files, a listing of available view variables and the complete SQL command of all queries are shown in separate panels:

The available plugins at this point are:

• Cache: Information on Zend_Cache and APC.
• Database: Full listing of SQL queries from Zend_Db and the time for each.
• Exception: Error handling of errors and exceptions.
• File: Number and size of files included with complete list.
• Html: Number of external stylesheets and javascripts. Link to validate with W3C. for custom memory measurements.
• Log: Timing information of current request, time spent in action controller and custom timers. Also average, min and max time for requests.
• Variables: View variables, request info and contents of $_COOKIE, $_POST and $_SESSION

Installation & Usage

To install, place the folder 'ZFDebug' in your library path, next to the Zend folder. Then add the following method to your bootstrap class (in ZF1.8+):

protected function _initZFDebug()
{
    $autoloader = Zend_Loader_Autoloader::getInstance();
    $autoloader->registerNamespace('ZFDebug');

    $options = array(
        'plugins' => array('Variables', 
                           'Database' => array('adapter' => $db), 
                           'File' => array('basePath' => '/path/to/project'),
                           'Cache' => array('backend' => $cache->getBackend()), 
                           'Exception')
    );
    $debug = new ZFDebug_Controller_Plugin_Debug($options);

    $this->bootstrap('frontController');
    $frontController = $this->getResource('frontController');
    $frontController->registerPlugin($debug);
}

Doctrine2 Plugin

Here is example configuration for using the Doctrine2 Plugin:

protected function _initZFDebug()
{
	if (APPLICATION_ENV == 'development') {
		$autoloader = Zend_Loader_Autoloader::getInstance();
		$autoloader->registerNamespace('ZFDebug');
		$em = $this->bootstrap('doctrine')->getResource('doctrine')->getEntityManager();
		$em->getConnection()->getConfiguration()->setSQLLogger(new \Doctrine\DBAL\Logging\DebugStack());
		
		$options = array(
			'plugins' => array(
				'Variables',
				'ZFDebug_Controller_Plugin_Debug_Plugin_Doctrine2'	=> array(
					'entityManagers' => array($em),
				),
				'File'			=> array('basePath' => APPLICATION_PATH . '/application'),
				//'Cache'		=> array('backend' => $cache->getBackend()),
				'Exception',
				'Html',
				'Memory',
				'Time',
				'Registry',
			)
		);
		
		$debug = new ZFDebug_Controller_Plugin_Debug($options);
		$this->bootstrap('frontController');
		$frontController = $this->getResource('frontController');
		$frontController->registerPlugin($debug);
	}
}
