if(navigator.userAgent.match(/Android/i)) { alert('Is Android !'); } else { alert('Is Not Android !'); }

if(strstr($_SERVER['HTTP_USER_AGENT'],'Android')) { echo 'Is Android !'; } else { echo 'Is Not Android !'; }

function browsers(){ global $HTTP_USER_AGENT ; if (isset($HTTP_USER_AGENT)){ $sAgent = $HTTP_USER_AGENT; }else{ $sAgent = $_SERVER['HTTP_USER_AGENT']; } if (strpos($sAgent,'MSIE') !== false && strpos($sAgent,'mac') === false && strpos($sAgent,'Opera') === false){ $iVersion = (float)substr($sAgent,strpos($sAgent,'MSIE') + 5,3); return ($iVersion >= 5.5) ; }else if (strpos($sAgent,'Gecko/') !== false){ $iVersion = (int)substr($sAgent,strpos($sAgent,'Gecko/') + 6,8); return ($iVersion >= 20030210) ; }else{ return false; } }
