Phalcon Debugbar

Integrates PHP Debug Bar with Phalcon Framework.



  1. Normal request capturing
  2. Ajax request capturing
  3. Redirect request chain capturing
  4. Simple App, Multi module App and Micro App support
  5. Data collected persistent : save to Local File or MongoDB, or ElasticSearch
  6. Data storaged by sessionid, it's more firendly for team development.
  7. You can close inject debugbar, and on a new browser tab, visit /_debugbar/open to see data(and it alse can be disabled).
  8. Whoops Integration, and debugbar works well with it.
  9. Support palcon 1.3.x,2.x,3.x, PHP5.5~7.1

Quick start


  • install

    php composer.phar require --dev snowair/phalcon-debugbar
  • update

    php composer.phar update snowair/phalcon-debugbar

Modify index.php

  1. Set your App Instance to DI:

    $application = new Phalcon\Mvc\Application( $di ); // Important: mustn't ignore $di param . The Same Micro APP: new Phalcon\Mvc\Micro($di);
    $di['app'] = $application; //  Important
  2. Before handle app, register and boot debugbar provider.

    (new Snowair\Debugbar\ServiceProvider())->start();
    // after start the debugbar, you can do noting but handle your app right now.
    echo $application->handle()->getContent();
  3. optional to use Whoops, modify the index.php, add follow codes bellow the debugbar service start() method.

    (new \Snowair\Debugbar\Whoops\WhoopsServiceProvider($di));

Modify The ACL Code

Here is a example for INVO:

public function beforeDispatch(Event $event, Dispatcher $dispatcher)
        $auth = $this->session->get('auth');
        if (!$auth){
            $role = 'Guests';
        } else {
            $role = 'Users';
        $controller = $dispatcher->getControllerName();
        $action = $dispatcher->getActionName();
        /* Debugbar start */
        $ns = $dispatcher->getNamespaceName();
        if ($ns=='Snowair\Debugbar\Controllers') {
            return true;
        /* Debugbar end */
        $acl = $this->getAcl();
        $allowed = $acl->isAllowed($role, $controller, $action);
        if ($allowed != Acl::ALLOW) {
                'controller' => 'errors',
                'action'     => 'show401'
            return false;

Data Persistent

For file driver, the default directory for store debugbar data is Runtime/phalcon. If it doesn't exist, it will be created automatically. You can change it by reconfig.

For mongodb driver, You must install the mongodb extension and install the phplib : composer require mongodb/mongodb

For elastic driver, You must install the phplib : composer require elasticsearch/elasticsearch:some-version

About baseUri

Be aware of the baseUri configuration of your project, you must set a currect baseUri for your uri service.

If you are using apache, you should enable the Rewrite mod and have a .htaccess file under the baseUri directory.

If you are using nginx, you should enable the Rewrite mod and edit the location block of the server configuration like this:

    location @rewrite {
        # replace 'baseuri' to your real baseuri
        rewrite ^/baseuri/(.*)$ /baseuri/index.php?_url=/$1;


Use your config

Copy config/debugbar.php to your config directory, and change any settings you want. Then use your debugbar config file by:

(new Snowair\Debugbar\ServiceProvider('your-debugbar-config-file-path'))->start();

Send custom messages to debugbar

\PhalconDebug::startMeasure('start-1','how long');        // startMeasure($internal_sign_use_to_stop_measure, $label)
\PhalconDebug::addMeasurePoint('start');                  // measure the spent time from latest measurepoint to now.
\PhalconDebug::addMessage('this is a message', 'label');  // add a message using a custom label.
\PhalconDebug::info($var1,$var2, $var3, ...);  // add many messages once a time. See PSR-3 for other methods name.(debug,notice,warning,error,...)
\PhalconDebug::addMessageIfTrue('1 == "1"', 1=='1','custom_label'); // add message only when the second parameter is true
\PhalconDebug::addMessageIfTrue('will not show', 1=='0');
\PhalconDebug::addMessageIfFalse('1 != "0" ', 1=='0');       // add message only when the second parameter is false
\PhalconDebug::addMessageIfNull('condition is null', Null ); // add message only when the second parameter is NULL
\PhalconDebug::addMessageIfEmpty('condition is emtpy', $condition ); // add message only when the second parameter is empty
\PhalconDebug::addMessageIfNotEmpty('condition is not emtpy', $condition=[1] ); // add message only when the second parameter is not empty
\PhalconDebug::addException(new \Exception('oh , error'));
\PhalconDebug::stopMeasure('start-1');                    // stopMeasure($internal_sign_use_to_stop_measure)

Volt Functions:



{{ debug( var1, var2 )}}
{{ info( var1, var2 )}}
{{ addMessageIfTrue('$var === true', var ) }}

Multi Modules

Usually, You needn't modify any other files, if you follow rules bellow:

  1. All the services for cache has a name contain cache.
  2. All the services for db has a name start with db or end with db.
  3. Visit /_debugbar/open?m={modulename} to open a independent debugbar page.

If your service name is't match these rules, you need attach it to debugbar:

// service.php
$di->set('read-db-test',function(...)); // db service
$di->set('redis',function(...)); // cache service
if ( $di->has('debugbar') ) {
    $debugbar = $di['debugbar'];


  • I strongly suggest you to assign a host domain to your project, and set the baseUri of uri service to /.

  • For ajax/json request, the debug data only stored in the persistent directory as a json file. You can Load it to the debugbar form Openhandler(Open icon on the right).

  • If the debugbar does not work, the most likely reason is that one or more collectors triggered a error in the runtime. You can modify the debugbar config file, close collector one by one, retry it until found the collector cause problem.

  • For any problems, you can open an Issue on Github.
