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

$agent = check_wap(); if ( $agent
) { exit ; } // check if wap 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; } } |
