ecshop多重判断来访用户是否来自手机的方法

• 1.搜集资料，这个方法可以实现判断来访用户是否手机
  $ua = strtolower($_SERVER[‘HTTP_USER_AGENT’]);
  $uachar=”/(nokia|sony|ericsson|mot|samsung|sgh|lg|philips|panasonic|alcatel|lenovo|cldc|midp|coolpad|ktouch|tcl|oppo|doov|amoi|bbk|cect|amoi|zte|huawei|iphone|ipad|android|smartphone)/i”;
  if(($ua == ” || preg_match($uachar, $ua))&& !strpos(strtolower($_SERVER[‘REQUEST_URI’]),’wap’))
  {
  $Loaction = ‘mobile/’;
  if (!empty($Loaction))
  {
  ecs_header(“Location: $Loaction\n”);
  exit;
  }
  }

  2.根据上面这个和一些资料，做了改良，先判断是否比较老的手机，然后再判断是否智能机系统
  $ua = strtolower($_SERVER[‘HTTP_USER_AGENT’]);
  if(strpos(strtoupper($_SERVER[‘HTTP_ACCEPT’]),”VND.WAP.WML”) > 0){// 检查浏览器是否接受 WML.
  $Loaction = ‘mobile1/’;
  if (!empty($Loaction))
  {
  ecs_header(“Location: $Loaction\n”);
  exit;
  }
  }
  //$uachar = “/(nokia|sony|ericsson|mot|samsung|sgh|lg|philips|panasonic|alcatel|lenovo|cldc|midp|coolpad|k-touch|tcl|oppo|doov|amoi|bbk|cect|amoi|zte|huawei|iphone|ipad|android|smartphone)/i”;
  $uachar = “/(nokia|sony|ericsson|mot|samsung|sgh|lg|philips|panasonic|alcatel|lenovo|cldc|midp|coolpad|k-touch|tcl|oppo|doov|amoi|bbk|cect|amoi|zte|huawei|iphone|ipad|android|smartphone|blackberry|configuration\/cldc|hp |hp-|htc |htc_|htc-|iemobile|kindle|midp|mmp|motorola|mobile|nokia|opera mini|opera |Googlebot-Mobile|YahooSeeker\/M1A1-R2D2|android|iphone|ipod|mobi|palm|palmos|pocket|portalmmm|ppc;|smartphone|sonyericsson|sqh|spv|symbian|treo|up.browser|up.link|vodafone|windows ce|xda |xda_)/i”;
  if(($ua == ” || preg_match($uachar, $ua))&& !strpos(strtolower($_SERVER[‘REQUEST_URI’]),’wap’))
  {
  $Loaction = ‘mobile/’;
  if (!empty($Loaction))
  {
  ecs_header(“Location: $Loaction\n”);
  exit;
  }
  }

  3.// check if wap
  function check_wap(){if(stristr($_SERVER[‘HTTP_VIA’],”wap”)){// 先检查是否为wap代理，准确度高
  returntrue;}elseif(strpos(strtoupper($_SERVER[‘HTTP_ACCEPT’]),”VND.WAP.WML”) > 0){
  // 检查浏览器是否接受
  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’])){
  //检查USER_AGENT
  return true; }else{return false; } }
