本文介紹了PHP學習：PHP 實現判斷用戶是否手機訪問，希望對您有用。如果有疑問，可以聯系我們。
PHP應用隨著移動設備的普及,網站也會迎來越來越多移動設備的拜訪.用適應PC的頁面,很多時候對手機用戶不友好,那么有些時候,我們需要判斷用戶是否用手機拜訪,如果是手機的話,就跳轉到指定的手機友好頁面.這里就介紹一下,如何判斷用戶是否用手機拜訪.
PHP應用自定義的函數如下：
代碼如下:
$agent = check_wap();
if( $agent )
{
? header('Location: http://www.nowamagic.net');
? exit;
}
// check if wap
function check_wap(){
? // 先檢查是否為wap代理經銷,準確度高
? if(stristr($_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;?
?}
}
PHP應用再來一個從PHP框架剝離的判斷是否為手機移動終端的函數：
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;?
}
PHP應用代碼很簡單,功能很實用,非常得當將其放入項目中,希望小伙伴們能夠喜歡.
