php判斷手機訪問實現程式

網上找到的

手機訪問，原理是手機通過移動公司的Proxy 伺服器進行的訪問。那麼我們就可以理解是一台普通電腦使用了Proxy 伺服器。當手機通過Proxy 伺服器訪問的時候，http頭資訊會毫無疑問的包含一個資訊：via。這個資訊提供了有價值的判斷資訊。
例如河南移動取得的via資訊是：

http/1.1 hazz-b-gw001-wap(infox-wisg, huawei technologies)
河南聯通的via資訊是：

zxwap gateway,zte technologies

代碼

代碼如下	複製代碼
// check if wap by xhatfunction check_wap() {  return stristr($_SERVER['HTTP_VIA'],"wap") ? true : false; }

這樣做的結果是沒有人能偽造手機訪問，判斷絕對準確。自然，這樣對於網上流行的手機wap模擬器也做了屏蔽—-從根本上屏蔽。
這樣肯定不行。

在網上又看到這一樣一個

php判斷手機瀏覽器的函數，代碼如下，加入了對ipad和android的判斷

代碼如下

複製代碼

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

測試後還是有問題，不講你也知道，後來看到了wordpress的 function.php 檔案這樣一段

代碼如下

複製代碼

//判斷是否屬手機 function is_mobile() {  $user_agent = $_SERVER['HTTP_USER_AGENT'];  $mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio","au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte");  $is_mobile = false;  foreach ($mobile_agents as $device) {   if (stristr($user_agent, $device)) {    $is_mobile = true;    break;   }  }  return $is_mobile; }

在你web 加入

代碼如下	複製代碼
if( is_mobile() ){   include('手機訪問.php檔案即可');exit; }

解決這類問題的方法有很多，如果你不想這樣操作可直接使用次層網域了。
