PHP Random User Agent Generator

Written in PHP, this script will generate real User Agent strings with optional capabilities to specify OS, Browser, Mobile, ect. simply by passing a parameter to the function called to generate the User Agent string. Created with the intentions of eliminating footprints while scraping the web for content using cURL because a truly solution to generate a truly random User Agent was not availble.

Other Randomly Generated Segments

Version of Android with Device / build number strings, and variations of known UA's for specific devices.
Version for iphone, ipad, or ipod from iOS 7-10
Version of Windows from Windows Vista thru Windows 10
Version of Chrome/Firefox/Safari for major versions that are still commonly used
Randomly adds en-US; to some the user agents, as well as the U; flag

It's also easy to customize with random syntax parsing and random number generating, see Customizing User Agent below

Usage Summary

Require useragent.php in the file where the User Agent string will be generated. ..*php require_once __DIR__.'/userAgent.php';
Initialize the userAgent class ..*php $agent = new userAgent;
Call the generate function to generate a random User Agent string as many times as needed. ..*php $UAString = $agent->generate();

Example Usage

$agent = new userAgent();
$agent->generate();

Or a one liner for one time use

$userAgent = (new userAgent) ->generate();

Example Usage when specifying a single OS, Browser, or Mobile

You can specify either firefox, chrome, mobile, windows, mac, iphone, ipad, ipod, and android.

$agent = new userAgent();
$UAFireFox = $agent->generate('firefox'); // generates a firefox user agent on either windows or mac
$UAChrome = $agent->generate('chrome'); // generates a chrome user agent on either windows or mac
$UAMobile = $agent->generate('mobile'); // generates a mobile user agent for either iphone or android
$UAWindows = $agent->generate('windows'); // generates a windows user agent for either firefox or chrome
$UAMac = $agent->generate('mac'); // generates a mac user agent for either firefox or chrome
$UAiPhone = $agent->generate('iphone'); // generates an iphone user agent for iOS 7-10
$UAAndroid = $agent->generate('android'); // generates an android user agent for android versions 4.3-7.1, and includes randomly generated device and build number string that is correct for the version of android being displayed.

Customizing User Agent

You can edit the provided variables that the User Agent strings are generated from, using the syntax below to generate random or "spin" content. The syntax formatting works as shown below:

$randomExample = 'Android [7.1|6.0|5.1]; Samsung Galaxy[ Note III| S6| S7|]'; // will choose a random android version 7.1, 6.0 or 5.1, and either Note III, S6, S7, or Nothing will be returned in the second option.

Additional Syntax: Random number between specified range is formatted as follows

$randomWindows = 'Windows; Windows 6.:number0-3:'; // :number0-3: will generate a number 0-3

NOTE: Nesting is supported in the random or "spin" syntax

$version = 'Android [7.[1|0]|6.0|5.1]';// will work as expected

but nesting is NOT supported within the random number syntax

$version = 'Android :number5-:number6-7::'; // will NOT return any number, and ':number5-:number6-7::' will be returned.
$version = 'Android :number4-7:.:number0-1:'; // will return numbers 4.0, 4.1, 5.0, 5.1, 6.0, 6.1, 7.0, and 7.1
