The easiest way to install DebugBar is using Composer with the following requirement:
{
"require": {
"maximebf/debugbar": ">=1.0.0"
}
}
Alternatively, you can download the archive 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.
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;
}
});
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
use DebugBar\StandardDebugBar;
use DebugBar\JavascriptRenderer;
$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)
