This is the PHP library for the uap-core project.


Add ua-parser/uap-php to the require section of your composer.json file and run composer update.



require_once 'vendor/autoload.php';
use UAParser\Parser;

$ua = "Mozilla/5.0 (Macintosh; Intel Ma...";

$parser = Parser::create();
$result = $parser->parse($ua);

Using Your Own Custom regexes.php File

You can use your own regexes.php file if you've customized the official file. I strongly encourage you to push back any changes you may have so others can benefit. That said, to use your own do the following:

require_once 'vendor/autoload.php';
use UAParser\Parser;

$parser = Parser::create("path/to/custom/regexes.php");

Using ua-parser PHP Library from the Command Line

A command line utility is now included with the PHP library. The following commands are supported:

Get Usage Info

Provides simple usage information:

php bin/uaparser

Update the regexes.php File

Fetches an updated YAML file for ua-parser and overwrites the current regexes.php file. You can use the following as part of a cron job that runs nightly.

php bin/uaparser ua-parser:update [--no-backup]

By default creates a backup file. Use --no-backup to turn that feature off.

Convert an Existing regexes.yaml File to regexes.php

With the change to v2.0 you may have an existing and customized YAML file for ua-parser. Use the following to convert it to JSON.

php bin/uaparser ua-parser:convert [file]

Grab Just the Latest regexes.yaml File From the Repository

If you need to add a new UA it's easier to edit the original YAML and then convert it to JSON.

php bin/uaparser ua-parser:fetch [file]

Fetches an updated YAML file. Warning: This method overwrites any existing regexes.yaml file.

Parse a Single User Agent String

Parses a user agent string and dumps the results as a list.

php bin/uaparser ua-parser:parse "your user agent string"

Parse a Webserver Log File

Parses the supplied log file or log directory to test ua-parser. Saves the UA to a file when the UA or OS family aren't recognized or when the UA is listed as a generic smartphone or as a generic feature phone.

php bin/uaparser ua-parser:logfile [-f /path/to/logfile] [-d /path/to/logdir] [--include "*.gz"] [--exclude "*.gz"] errors.log

Multiple --include and --exclude parameters are allowed.
