# PHP Debug Bar Displays a debug bar in the browser with information from php. No more `var_dump()` in your code! ![Screenshot](https://raw.github.com/maximebf/php-debugbar/master/docs/screenshot.png) **Features:** - Generic debug bar with no other dependencies - Easy to integrate with any project - Clean, fast and easy to use interface - Handles AJAX request - Includes generic data collectors and collectors for well known libraries - The client side bar is 100% coded in javascript - Easily create your own collectors and their associated view in the bar ## Installation The easiest way to install DebugBar is using [Composer](https://github.com/composer/composer) with the following requirement: { "require": { "maximebf/debugbar": ">=1.0.0" } } Alternatively, you can [download the archive](https://github.com/maximebf/php-debugbar/zipball/master) and add the src/ folder to PHP's include path: set_include_path('/path/to/src' . PATH_SEPARATOR . get_include_path()); DebugBar does not provide an autoloader but follows the [PSR-0 convention](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-0.md). You can use the following snippet to autoload DebugBar classes: spl_autoload_register(function($className) { if (substr($className, 0, 8) === 'DebugBar') { $filename = str_replace('\\', DIRECTORY_SEPARATOR, trim($className, '\\')) . '.php'; require_once $filename; } }); ## Quick start DebugBar is very easy to use and you can add it to any of your projets in no time. The easiest way is using the `render()` functions getJavascriptRenderer(); $debugbar["messages"]->addMessage("hello world!"); ?> renderHead() ?> ... render() ?> 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 all bundled collectors: - `MemoryCollector` (*memory*) - `MessagesCollector` (*messages*) - `PhpInfoCollector` (*php*) - `RequestDataCollector` (*request*) - `TimeDataCollector` (*time*) - `ExceptionsCollector` (*exceptions*) Learn more about DebugBar in the [docs](http://phpdebugbar.com/docs).
