PHP获取用户设备信息判断是苹果还是安卓还是其他：$_SERVER['HTTP_USER_AGENT']

$temUrl = $temApp['android'];
if (dstrpos($_SERVER['HTTP_USER_AGENT'], ['iphone', 'ipad', 'ipod', 'mac', 'ios', 'playbook'])) {
    $temUrl = $temApp['ios'];
} else if (dstrpos($_SERVER['HTTP_USER_AGENT'], ['android', 'Windows'])) {
    $temUrl = $temApp['android'];
}

redirect($temUrl);die;



//自定义函数：
//dstrpos 函数用于检查给定的字符串 $string 中是否包含数组 $arr 中的任意一个子字符串。如果包含，则返回 true，否则返回 false

function dstrpos($string, $arr)
{
    if (!empty($string)) {
       foreach ((array) $arr as $_var_136) {
          if (strpos(strtolower($string), $_var_136) !== false) {
             return true;
          }
       }
    }
    return false;
}
//跳转页面

function redirect($url = '/', $code = '')
{
    if ($code == 301) {
       header("HTTP/1.1 301 Moved Permanently");
    }
    exit(header("location:" . $url));
}
