The best way to install DebugBar is using Composer with the following command:
composer require --dev php-debugbar/php-debugbar
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.
