PHP判断访问用户是否使用手机访问

随着移动设备的普及,网站也会迎来越来越多移动设备的访问。当然我们可以使用响应式设计来使网站页面既适应PC端也适应移动端,但很多时候我们还需要判断用户是否使用移动端访问,以实现某些特定的功能。这里就介绍一下,如何判断用户是否用手机访问。

自定义的函数如下:
$agent = check_wap();
if( $agent )
{
	header('Location: http://www.nowamagic.net');
	exit;
}

function check_wap(){
	// 先检查是否为wap代理,准确度高
	if(stristr($_SERVER['HTTP_VIA'],"wap")){
		return true;
	}
	// 检查浏览器是否接受 WML.
	elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){
		return true;
	}
	//检查USER_AGENT
	elseif(preg_match('/(blackberry|configuration\/cldc|hp |hp-|htc |htc_|htc-|iemobile|kindle|midp|mmp|motorola|mobile|nokia|opera mini|opera |Googlebot-Mobile|YahooSeeker\/M1A1-R2D2|android|iphone|ipod|mobi|palm|palmos|pocket|portalmmm|ppc;|smartphone|sonyericsson|sqh|spv|symbian|treo|up.browser|up.link|vodafone|windows ce|xda |xda_)/i', $_SERVER['HTTP_USER_AGENT'])){
		return true;		 	
	}
	else{
		return false;	
	}
}
下面是一个从PHP框架剥离的判断是否为手机移动终端的函数:
function is_mobile_request()   
{   
	$_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : '';   
	$mobile_browser = '0';

	if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT'])))   
		$mobile_browser++;   
	if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))   
		$mobile_browser++;   
	if(isset($_SERVER['HTTP_X_WAP_PROFILE']))   
		$mobile_browser++;   
	if(isset($_SERVER['HTTP_PROFILE']))   
		$mobile_browser++;

	$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));   
	$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($mobile_ua, $mobile_agents))   
		$mobile_browser++;   
	if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false)   
		$mobile_browser++;    
	if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false)   
		$mobile_browser=0;   
	if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false)   
		$mobile_browser++;   
	if($mobile_browser>0)   
		return true;   
	else 
		return false;   
}
