PHP识别电脑还是手机访问网站

最近在做phongap的项目，同一套代码，支持pc可以调试，又支持手机app调用接口，如果在pc上不屏掉调用接口js会报错，难以加载

，所以就在网上找了，这个，不是原创，重在分享。

<?php
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;
			}
			return false;
	}
	$mobile_os_list=array('Google Wireless Transcoder','Windows CE','WindowsCE','Symbian','Android','armv6l','armv5','Mobile','CentOS','mowser','AvantGo','Opera Mobi','J2ME/MIDP','Smartphone','Go.Web','Palm','iPAQ');
	$mobile_token_list=array('Profile/MIDP','Configuration/CLDC-','160×160','176×220','240×240','240×320','320×240','UP.Browser','UP.Link','SymbianOS','PalmOS','PocketPC','SonyEricsson','Nokia','BlackBerry','Vodafone','BenQ','Novarra-Vision','Iris','NetFront','HTC_','Xda_','SAMSUNG-SGH','Wapaka','DoCoMo','iPhone','iPod');  

	$found_mobile=CheckSubstrs($mobile_os_list,$useragent_commentsblock) ||
			  CheckSubstrs($mobile_token_list,$useragent);  

	if ($found_mobile){
		return true;
	}else{
		return false;
	}
}
if (isMobile())
	echo '手机登录';
else
	echo '电脑登录';
?>

试一下，还行，现在只是针对自己调试，不什么问题
