 function isMobile(){  
 	$useragent=isset($_SERVER['HTTP_USER_AGENT']) ? $_SERVER['HTTP_USER_AGENT'] : '';  
 	$useragent_commentsblock=preg_match('|\(.*?\)|',$useragent,$matches)>0?$matches[0]:'';     
 	function CheckSubstrs($substrs,$text){    
 		foreach($substrs as $substr)     
 			if(false!==strpos($text,$substr)){      
 				return true;     
 			}

 	$found_mobile=CheckSubstrs($mobile_os_list,$useragent_commentsblock) || CheckSubstrs($mobile_token_list,$useragent);  
 	if ($found_mobile){    
 		return true;  
 	}else{
