判断用户是否手机访问

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。用适应PC的页面,很多时候对手机用户不友好,那么有些时候,我们需要判断用户是否用手机访问,如果是手机的话,就跳转到指定的手机友好页面。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:

<?php
$agent = check_wap();
if($agent){
	header('Location: http://www.uuling.com');
	exit;
}

/**
 * 检测是否为手机访问
 */
function check_wap(){
	//先检测是否为wap代理
	if(isset($_SERVER['HTTP_VIA']) && stristr($_SERVER['HTTP_VIA'], 'wap')){
		return true;
	}elseif(isset($_SERVER['HTTP_ACCEPT']) && strpos(strtoupper($_SERVER['HTTP_ACCEPT']), 'VND.WAP.WML') !== false){
		//检查浏览器是否接受 WML.
		return true;
	}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'])){
		//检查USER_AGENT
		return true;
	}else{
		return false;
	}
}

再来一个从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'])) && (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)
		$mobile_browser++;
	// Pre-final check to reset everything if the user is on Windows
	if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false)
		$mobile_browser=0;
	// But WP7 is also Windows, with a slightly different characteristic
	if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false)
		$mobile_browser++;
	if($mobile_browser>0)
		return true;
	else 
		return false;
}
