Foolz\Profiler

This package provides a simple to use profiler, with the power of monolog.

Requirements

• PHP 5.4 or higher
• Monolog (automatically installed with composer)

Installation

Install as any composer package.

Setup

You should load the profiler early in your code.

<?php
$profiler = new Profiler();
$profiler->enable();

Until enable isn't run, no request will be logged. You can setup monolog handlers to have custom output options:

<?php
$profiler = new Profiler();
$profiler->pushHandler(new ChromePHPHandler());
$profiler->enable();

$profiler->log("Profiler enabled");

HTML output

Remember to check whether you have a text/html request before inserting the HTML profiler panel.

You can print the current log at any time with $profiler->getHtml().

If you use a framework you might have a $response variable that handles the data sent to the client. To put the profiler at the bottom of the page, you may try something similar to the following.

<?php
$content = explode('</body>', $response->getContent());
if (count($content) == 2) {
    $response->setContent($content[0].$this->profiler->getHtml().$content[1]);
}

$response->send();

Methods

• pushHandler() As Monolog's pushHandler() function, allows adding log handlers to the logger

• getLogger() Returns the Monolog logger so it can be customized

• enable() Enables the profiler and prints how much time was elapsed since the start of the script

• isEnabled() Tells if the profiler is enabled

• log($string, $context) Logs elapsed time since the beginning of the script and total memory usage The $string variable allows setting a string to identify the entry in the log The $context variable allows adding arbitrary data to the entry

• logMem($string, $variable, $context) Logs memory usage of $variable. While checking, a clone of $variable will be created (it can't be helped), so use with caution. For the rest, it works like log()

• logStart($string, $context) Like log() but it starts a timer

• logStop($string, $context) Like log(), but if called after logStart(), $context will contain elapsed time

• getHtml() Returns an HTML representation of the logged entries
