Js vs php 判断系统

JS

function IOSVersion() {
    var ua = navigator.userAgent.toLowerCase()
    var phoneReg = /(iphone|ipod|((?:android)?.*?mobile)|j2me|mobi|blackberry|nokia|maemo|mini)/i
    if (phoneReg.test(ua)) {
      var ver = ua.match(/ os (.*?) like mac os/)
      if (ver) {
        return ver[1].replace(/_/g, '.')
      }
    }
    return false
}

function isAndroid() {
  var ua = navigator.userAgent.toLowerCase()
  var phoneReg = /android/i
  if (phoneReg.test(ua)) {
    return true
  }
  return false
}

php

function get_device_type()
{
//全部变成小写字母
    $agent = strtolower($_SERVER['HTTP_USER_AGENT']);
    $type = 'other';
//分别进行判断
    if (strpos($agent, 'iphone') || strpos($agent, 'ipad')) {
        $type = 'ios';
    }
    if (strpos($agent, 'android')) {
        $type = 'android';
    }
    return $type;
}
