PHP 實現判斷使用者是否手機訪問，php判斷

隨著行動裝置的普及，網站也會迎來越來越多行動裝置的訪問。用適應PC的頁面，很多時候對手機使用者不友好，那麼有些時候，我們需要判斷使用者是否用手機訪問，如果是手機的話，就跳轉到指定的手機友好頁面。這裡就介紹一下，如何判斷使用者是否用手機訪問。

自訂的函數如下：

複製代碼 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;
}
}

再來一個從PHP架構剝離的判斷是否為手機移動終端的函數：

複製代碼 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;
}

代碼很簡單，功能很實用，非常適合將其放入項目中，希望小夥伴們能夠喜歡。
