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, APC and Zend OPcache (for PHP 5.5).
- 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.
- Session
- Variables: View variables, request info and contents of $_COOKIE, $_POST and $_SESSION

Using Composer
You may now install ZFDebug using the dependency management tool Composer.
To use ZFDebug with Composer, add the following to the require list in your project's composer.json file:
"require": {
"tavy315/zfdebug": "1.*"
},
Run the install command to resolve and download the dependencies:
php composer.phar install
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);
}
Sample Zend Plugin to load the ZFDebug toolbar
Some use case will require that you set up callback functions. Especially, these happen to occur in the following plugins:
- cache: the callback function is called when asked to clean the cache
- language: the callback is called when we try to change the active language
- auth: the callback is used to retrieve the real username when the default plugin would only give an id
You can leverage those functionalities by setting the following class:
<?php
class Application_Controller_Plugin_Debug extends \ZFDebug\Controller\Plugin\Debug
{
public function __construct($options = null)
{
// avoids constructing before required vars are available
}
public function preDispatch(\Zend_Controller_Request_Abstract $request)
{
if (APPLICATION_ENV !== 'production') {
$auth_callback = function ($raw_user) {
// do the job for getting the real username from the raw data you would typically retrieve
};
$locale_callback = function () {
// do the job for changing locale
};
$cache_callback = function () {
// do the job for clearing the cache
};
$this->_options = array(
'image_path' => null,
'plugins' => array(
'Variables',
'Doctrine2' => array(
'entityManagers' => array(
\Zend_Registry::get('em')
),
),
'File' => array(
'base_path' => APPLICATION_PATH . '/../',
),
'Cache' => array(
'backend' => 'Zend_Cache',
'callback' => $cache_callback,
),
'Exception',
'Html',
'Locale' => array(
'callback' => $locale_callback,
),
'Auth' => array(
'user' => 'id',
'callback' => $auth_callback,
),
)
);
// Registering Debug plugin
parent::__construct();
}
}
}
Doctrine 1 Plugin
Here is example configuration for using the Doctrine Plugin:
protected function _initZFDebug()
{
if (APPLICATION_ENV === 'development') {
$options = array(
'plugins' => array(
'Variables',
'File',
'Memory',
'Time',
'Doctrine1',
'Exception'
)
);
$ZFDebug = new \ZFDebug\Controller\Plugin\Debug($options);
$frontController = \Zend_Controller_Front::getInstance();
$frontController->registerPlugin($ZFDebug);
return $ZFDebug;
}
}
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());
$options = array(
'plugins' => array(
'Variables',
'Doctrine2' => array(
'entityManagers' => array($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);
}
}
