  "require": {
    "woothee/woothee": "*"


Parsing user-agent

$classifier = new \Woothee\Classifier;

$r = $classifier->parse('user agent string');

// => name of browser (or string like name of user-agent)

// => "pc", "smartphone", "mobilephone", "appliance", "crawler", "misc", "unknown"

// => os from user-agent, or carrier name of mobile phones

// => version of browser, or terminal type name of mobile phones

// => version of operating systems (for some typical cases)

Parse user-agent string and returns a array with keys name, category, os, version and vendor.
