Readme
parseUserAgent is a function that takes a user agent and returns the name and version of the corresponding browser & operating system.
There are many libraries and solutions for this problem, but I decided to re-invent the wheel and write my own as I've not found one that did all of the following:
<?php
$user_agent = $_SERVER['HTTP_USER_AGENT'];
// Mozilla/5.0 (Linux; Android 10; BLA-L09) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.96 Mobile Safari/537.36 (Ecosia android@78.0.3904.96)
print_r(
parseUserAgent($user_agent)
);
The above code will output:
Array
(
[browser_name] => Ecosia Browser
[browser_version] => android@78.0.3904.96
[operating_system_name] => Android
[operating_system_version] => 10
[is_mobile] => 1
)
let user_agent = request.headers["user-agent"];
// Mozilla/5.0 (Linux; Android 10; BLA-L09) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.96 Mobile Safari/537.36 (Ecosia android@78.0.3904.96)
console.table(parseUserAgent(user_agent));
The above code will output:
┌──────────────────────────┬────────────────────────┐
│ (index) │ Values │
├──────────────────────────┼────────────────────────┤
│ browser_name │ 'Ecosia Browser' │
│ browser_version │ 'android@78.0.3904.96' │
│ operating_system_name │ 'Android' │
│ operating_system_version │ '10' │
│ is_mobile │ true │
└──────────────────────────┴────────────────────────┘
Included in both PHP and JavaScript versions, is a function to convert Windows versions to public names:
let user_agent = request.headers["user-agent"];
// Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN) AppleWebKit/523.15 (KHTML, like Gecko, Safari/419.3) Arora/0.3 (Change: 287 c9dfb30)
let user_agent_parsed = parseUserAgent(user_agent);
console.table(user_agent_parsed);
user_agent_parsed = parseWindowsVersion(user_agent_parsed);
console.table(user_agent_parsed);
The above code will output:
┌──────────────────────────┬───────────┐
│ (index) │ Values │
├──────────────────────────┼───────────┤
│ browser_name │ 'Arora' │
│ browser_version │ '0.3' │
│ operating_system_name │ 'Windows' │
│ operating_system_version │ '5.1' │
│ is_mobile │ false │
└──────────────────────────┴───────────┘
┌──────────────────────────┬───────────┐
│ (index) │ Values │
├──────────────────────────┼───────────┤
│ browser_name │ 'Arora' │
│ browser_version │ '0.3' │
│ operating_system_name │ 'Windows' │
│ operating_system_version │ 'XP' │
│ is_mobile │ false │
└──────────────────────────┴───────────┘
Function accepts either a JavaScript object/PHP array with "operating_system_version" key, or just a string:
console.log(parseWindowsVersion("5.1")); // XP
