隨著移動(dòng)設(shè)備的普及，網(wǎng)站也會(huì)迎來(lái)越來(lái)越多移動(dòng)設(shè)備的訪問(wèn)。用適應(yīng)PC的頁(yè)面，很多時(shí)候?qū)?a href=/pingce/shouji/ target=_blank class=infotextkey>手機(jī)用戶(hù)不友好，那么有些時(shí)候，我們需要判斷用戶(hù)是否用手機(jī)訪問(wèn)，如果是手機(jī)的話，就跳轉(zhuǎn)到指定的手機(jī)友好頁(yè)面。這里就介紹一下，如何判斷用戶(hù)是否用手機(jī)訪問(wèn)。

自定義的函數(shù)如下：
復(fù)制代碼 代碼如下:
$agent = check_wap();
if( $agent )
{
    header('Location: http://www.nowamagic.NET');
    exit;
}

// check if wap
function check_wap(){
    // 先檢查是否為wap代理，準(zhǔn)確度高
    if(stristr($_SERVER['HTTP_VIA'],"wap")){
        return true;
    }
    // 檢查瀏覽器是否接受 WML.
    elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){
        return true;
   }
   //檢查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;   
   }
}

再來(lái)一個(gè)從php框架剝離的判斷是否為手機(jī)移動(dòng)終端的函數(shù)：（經(jīng)過(guò)測(cè)試，很全面，推薦使用）
復(fù)制代碼 代碼如下:
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)  
    $mobile_browser++;  
  // Pre-final check to reset everything if the user is on Windows  
  if(strpos(strtolower($_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;
