Installation

The best way to install DebugBar is using Composer with the following command:

composer require maximebf/debugbar --dev

Quick start

DebugBar is very easy to use and you can add it to any of your projects in no time. The easiest way is using the render() functions

<?php

// Require the Composer autoloader, if not already loaded
require 'vendor/autoload.php';

use DebugBar\StandardDebugBar;

$debugbar = new StandardDebugBar();
$debugbarRenderer = $debugbar->getJavascriptRenderer();

$debugbar["messages"]->addMessage("hello world!");
?>
<html>
    <head>
        <?php echo $debugbarRenderer->renderHead() ?>
    </head>
    <body>
        ...
        <?php echo $debugbarRenderer->render() ?>
    </body>
</html>

The DebugBar uses DataCollectors to collect data from your PHP code. Some of them are automated but others are manual. Use the DebugBar like an array where keys are the collector names. In our previous example, we add a message to the MessagesCollector:

$debugbar["messages"]->addMessage("hello world!");

StandardDebugBar activates the following collectors:

  • MemoryCollector (memory)
  • MessagesCollector (messages)
  • PhpInfoCollector (php)
  • RequestDataCollector (request)
  • TimeDataCollector (time)
  • ExceptionsCollector (exceptions)

Learn more about DebugBar in the docs.
