如何用PHP区分移动设备和桌面浏览器,“正确”的方法是使用一个完整的设备检测数据库等DeviceAtlas.所以我们查找各类资料，以下最模板提供的php代码囊括各类手机平板的最全的识别方法，最齐全的！

<?php
//www.zuimoban.com
 $mobile_browser = '0';
 if (preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|android)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) {
    $mobile_browser++;
}
 if ((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') > 0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_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') > 0) {
    $mobile_browser++;
}
 if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows') > 0) {
    $mobile_browser = 0;
}
 if ($mobile_browser > 0) {
   // do something
}
else {
   // do something else
}   
 ?>

改php代码能达到如下效果
 

• 添加W3C用户代理字符串(默认交付上下文)
• Opera Mini的特殊情况检测
• 全方位异常设备与Windows在UA字符串(Opera 9为Windows被公认为移动设备)
• Android用户代理代码片段添加
