当用户使用手机等移动终端访问网站时，咱们能够经过程序检测用户终端类型，若是是手机用户，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。前端
咱们使用PHP的$_SERVER['HTTP_USER_AGENT']来获取手机用户浏览器的用户代理，而后匹配已有的各类手机浏览器代理库，若是含有匹配的关键字，则判断为手机（移动终端）用户。android
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; }
您也能够直接在前端页面上加入一段Javascript脚原本判断用户的终端类型。Javascript也是经过获取浏览器的user-agent信息，而后匹配已有的user-agent信息库。ios
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');}
