PHP和JS判断手机还是电脑访问

当用户使用手机等移动终端访问网站时，我们可以通过程序检测用户终端类型，如果是手机用户，则引导用户访问适配手机屏幕的移动站点。本文将介绍分别使用PHP和JAVASCRIPT代码判断用户终端类型。

PHP版

我们使用PHP的$_SERVER['HTTP_USER_AGENT']来获取手机用户浏览器的用户代理，然后匹配已有的各种手机浏览器代理库，如果含有匹配的关键字，则判断为手机（移动终端）用户。

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","iphone","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;

}

Javascript版

您也可以直接在前端页面上加入一段Javascript脚本来判断用户的终端类型。Javascript也是通过获取浏览器的user-agent信息，然后匹配已有的user-agent信息库。

if (navigator.userAgent.match(/(iPhone|iPod|Android|ios|iOS|iPad|Blackerry|WebOS|Symbian|Windows Phone|Phone|Nokia|UCWEB)/i)) {
    alert('手机');
}else{
    alert('PC');
}
