php判断手机客户端
- 发表于
- WordPress
前几日为一客户定制一个wp主题，要求手机浏览，找了一些资料，写了一个php判断手机浏览器的函数，代码如下，加入了对ipad和android的判断
|
1 2 3 4 5 6 7 8 9 |
<?php // check if wap function check_wap(){ if(stristr($_SERVER['HTTP_VIA'],"wap")){// 先检查是否为wap代理，准确度高 return true; }elseif(strpos(strtoupper($_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; } } |
基本上用于wp的wap插件也可以不用了，直接用这个函数就好了

user-agent判断一枚

1 2 3 4 5 6 7 8 9 10 11 12 13 |
//判断是否属手机 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","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; } |
使用
|
1 2 3 |
if( is_mobile() ){ echo '您使用的是移动设备访问'; } |
相对精准的判断
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 |
function is_Mobile_Device(){ //获取ALL_HTTP全部的http信息 $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : ''; $mobile_browser = '0'; if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) $mobile_browser++; if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false)) $mobile_browser++; if(isset($_SERVER['HTTP_X_WAP_PROFILE'])) $mobile_browser++; if(isset($_SERVER['HTTP_PROFILE'])) $mobile_browser++; $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4)); $mobile_agents = array( 'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac', 'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno', 'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-', 'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-', 'newt','noki','oper','palm','pana','pant','phil','play','port','prox', 'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar', 'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-', 'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp', 'wapr','webc','winw','winw','xda','xda-' ); if(in_array($mobile_ua, $mobile_agents)) $mobile_browser++; if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false) $mobile_browser++; if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false) $mobile_browser=0; if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false) $mobile_browser++; if($mobile_browser>0) return true; else return false; } |
简单通过user-agent方式判断
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
function isMobileDevice() { if(isset($_SERVER['HTTP_USER_AGENT'])) { //判断获取客户端标识 $userAgent = strtolower($_SERVER['HTTP_USER_AGENT']); $clientkeywords = array( 'nokia', 'sony', 'ericsson', 'mot', 'samsung', 'htc', 'sgh', 'lg', 'sharp', 'sie-' ,'philips', 'panasonic', 'alcatel', 'lenovo', 'iphone', 'ipod', 'blackberry', 'meizu', 'android', 'netfront', 'symbian', 'ucweb', 'windowsce', 'palm', 'operamini', 'operamobi', 'opera mobi', 'openwave', 'nexusone', 'cldc', 'midp', 'wap', 'mobile' ); // 从获取的HTTP_USER_AGENT中查找手机浏览器关键字进行判断 if(preg_match("/(".implode('|',$clientkeywords).")/i",$userAgent)&&strpos($userAgent,'ipad') === false) { return true; } } return false; } |
PHP通过http头user-agent判断是否为手机浏览器
下面PHP自定义函数可以根据http头user-agent判断是否为手机访问，如果是则返回true：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
<?php /** * 判断是否是通过手机访问 * @return bool 是否是移动设备 */ public function isMobile() { //判断手机发送的客户端标志 if(isset($_SERVER['HTTP_USER_AGENT'])) { $userAgent = strtolower($_SERVER['HTTP_USER_AGENT']); $clientkeywords = array( 'nokia', 'sony', 'ericsson', 'mot', 'samsung', 'htc', 'sgh', 'lg', 'sharp', '' ,'philips', 'panasonic', 'alcatel', 'lenovo', 'iphone', 'ipod', 'blackberry', 'meizu', 'android', 'netfront', 'symbian', 'ucweb', 'windowsce', 'palm', 'operamini', 'operamobi', 'opera mobi', 'openwave', 'nexusone', 'cldc', 'midp', 'wap', 'mobile' ); // 从HTTP_USER_AGENT中查找手机浏览器的关键字 if(preg_match("/(".implode('|',$clientkeywords).")/i",$userAgent)&&strpos($userAgent,'ipad') === false) { return true; } } return false; } |
上面看似好多个，其实都差不多，找一个合适的改改完善下又是一个新的了，判断的标识也就那么几个，用法也一样，另外可以单独做判断，如：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
//获取USER AGENT $agent = strtolower($_SERVER['HTTP_USER_AGENT']); //分析数据 $is_pc = (strpos($agent, 'windows nt')) ? true : false; $is_iphone = (strpos($agent, 'iphone')) ? true : false; $is_ipad = (strpos($agent, 'ipad')) ? true : false; $is_android = (strpos($agent, 'android')) ? true : false; //输出数据 if($is_pc){ echo "这是PC"; } if($is_iphone){ echo "这是iPhone"; } if($is_ipad){ echo "这是iPad"; } if($is_android){ echo "这是Android"; } |
如果你只判断是否为iphone设备可以如下来进行操作,代码如下:
|
1 2 3 4 5 6 7 8 9 10 11 |
function get_device_type(){ $agent = strtolower($_SERVER['HTTP_USER_AGENT']); $type = 'other'; if(strpos($agent, 'iphone') || strpos($agent, 'ipad') ){ $type = 'ios'; } if(strpos($agent, 'android')){ $type = 'android'; } return $type; } |
多数使用user-agent判断就行，根据生产环境来确定。例如微信就是使用了user-agent+id来验证，相比user-agent多了一道验证，但抓包修改两个地方同样能模拟。
