Q:

Detecting the stock android browser with PHP?

As many of you might have encountered, the stock Android browser, thankfully discontinued in Android 4.4 is more or less the modern IE6 - riddled with bugs and broken to the point of inciting suicide amongst developers. Consequently, the need to serve resources specific to that browser is quickly becoming a necessity, and the best way to do that would be by linking stylesheets/js through the back end. So what's a fool proof way of detecting the browser using PHP? 

A:

Thankfully it's pretty simple:
//get the user agent string
$ua = $_SERVER['HTTP_USER_AGENT'];

//results array
$matches = [];

//perform regex query
preg_match ( '/Android.*AppleWebKit\/([\d.]+)/', $ua, $matches);

//Check if the regex query returned matches specific to 
//the android stock browser.
if( isset($matches[0]) && 

  //This is where we diffrentiate the stock browser from chrome, 
  //the default browser's webkit version never goes above 537
  ( isset($matches[1]) && intval($matches[1] < 537) ) ){
    echo 'Browsing via stock android browser';
}

Please add your improved answers.
