How To Identify Mobile Browsers Using PHP

Left Quote There are all sorts of overly-complicated functions to identify whether the user has a mobile browser or a desktop. This function is nice and clean, and returns either true (if mobile) or false (if not).

function mobile_browser() {

  if (preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|pad|phone|

  android)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) return true;

  if ((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml')>0)

   OR ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['HTTP_PROFILE'])))) 

  return true;



  $mobile_agents = array(

    'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',

    'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',

    'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',

    'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',

    'newt','noki','oper','palm','pana','pant','phil','play','port','prox',

    'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',

    'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',

    'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',

    'wapr','webc','winw','winw','xda ','xda-'); 



    if (in_array(strtolower(substr($_SERVER['HTTP_USER_AGENT'], 0, 4)),$mobile_agents)) 

    return true;

    else return false;

}

To call, it just use the following:

if (mobile_browser()) print "mobile";

else print "desktop";

Nice and simple. If you see anything that gets through, please let me know and I'll update the function. Right Quote
