PHP Browser Detection

A PHP library for detecting the browser, operating system (OS), platform, and device type through User-Agent parsing, designed with a focus on high performance and minimal memory usage during HTTP client parsing.\ It uses a simple yet fast algorithm to accurately identify over 200 browsers/apps and more than 60 OS.\ Parsing the most common browsers takes less than 0.0005 seconds, even on low-end shared hosting environments. For rare User-Agents, recognition times are under 0.0008 seconds in the same hosting conditions.\ The library is exclusively tailored for current browsers and OS, omitting support for outdated environments that are no longer in use.\ The library operates using a single file and does not rely on any third-party dependencies.

Requirements

This library requires PHP 5.3 or later.

Manual installation

  1. Simply upload the library file BrowserDetection.php (located in the src directory) to your project;
  2. Include the PHP library file using require_once:
<?php

require_once('BrowserDetection.php');

?>

Installation by using Composer

Install this library using Composer:

composer require foroco/php-browser-detection

Update library package by running a command:

composer update foroco/php-browser-detection

The first step requires the Composer autoloader:

<?php

require ('vendor/autoload.php');

// If you use PHP in Windows OS use another path style:
// require ('vendor\autoload.php');
?>

Usage

The library attempts to retrieve environment data from the HTTP_USER_AGENT header sent by the HTTP client.\ The BrowserDetection PHP class within this library provides four public methods that return either an array or a JSON string containing the detected data extracted from the HTTP_USER_AGENT:

First argument should contain User-Agent string from the HTTP_USER_AGENT header or your custom User-Agent string.\ Second argument (optional) may contain 'JSON' if you want to get returned result as JSON format.

<?php

$Browser = new foroco\BrowserDetection();

$useragent = $_SERVER['HTTP_USER_AGENT'];

// Get all possible environment data (array):
$result = $Browser->getAll($useragent);

// Get OS data (array):
$result = $Browser->getOS($useragent);

// Get Browser data (array):
$result = $Browser->getBrowser($useragent);

// Get Device type data (array):
$result = $Browser->getDevice($useragent);

/*
Also methods may returned result as JSON string
Just use second argument of methods as 'JSON'
*/

// Get all possible environment data (JSON):
$result = $Browser->getAll($useragent, 'JSON');

print_r($result);

// ... etc
?>

The library class BrowserDetection also contains special method setTouchSupport() (optional, available from version 1.1).\ This method is necessary to detect mobile browsers in Desktop Mode condition (Android and iOS).\ For Desktop Mode detection setTouchSupport() method should call if browser supports Touch events.\ Touch events detection is performed by client-side JavaScript code in the target browser. Example:

if (('ontouchstart' in window) || window.DocumentTouch && document instanceof DocumentTouch) {
// Touch Event detected
}

Description for returned variables

Benchmarking Test

Benchmarking was performed on a low-level shared hosting environment.\ Test server configuration: RedHat Linux + LiteSpeed + PHP Extension.\ Test conditions based on collection of random ~446000 non repeated real life User-Agent strings.

User-Agent recognition performance in PHP 7.3 (requests per second):

getAll: ~ 31000 rps
getOS: ~ 120000 rps
getBrowser: ~ 43000 rps
getDevice: ~ 70000 rps

Important notice

Unfortunately, the major browser engines have "frozen" the OS version information in the User-Agent header.\ For example, on macOS, the OS version information in the User-Agent is "frozen" at the macOS Big Sur release level (Mac OS X 10_15_7).\ On Windows, the OS version information is "frozen" in the User-Agent at the Windows 10 release level (Windows NT 10.0).

Recent releases of WebKit, Chromium, and Gecko-based browsers no longer include correct current OS version information in the User-Agent header.

See reference:

https://issues.chromium.org/issues/40167872 \ https://bugzilla.mozilla.org/show_bug.cgi?id=1679929 \ https://bugs.webkit.org/show_bug.cgi?id=217364

One approach is to use the HTTP Client Hints headers, specifically the Sec-CH-UA-Platform-Version header. It's important to note, however, that only Chromium-based browsers currently support sending Client Hints headers.
