The memory_get_usage and memory_get_peak_usage functions have a $real_usage parameter. Update the MemoryCollector and PDOCollector collectors to use a value of false instead of true. For MemoryCollector, we allow the user to choose which type of memory usage to gather. To recap, when $real_usage is set (and previously this was the hard-coded default), PHP returns the amount of memory allocated from the operating system by the PHP memory manager. This is typically done in large chunks of memory and is not very granular. When $real_usage is cleared, PHP returns the amount of memory the user’s application has actually allocated from the PHP memory manager. Clearing $real_usage has useful application especially for the PDOCollector. As an example, a query that returns only a few rows will often say that zero bytes were used when $real_usage is set. That’s because PHP was able to satisfy the memory requests from memory it had already allocated from the operating system. To contrast, the same query will show an expected few kilobytes of memory usage when $real_usage is set to false.

Installation
The best way to install DebugBar is using Composer with the following command:
composer require maximebf/debugbar
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)
