代码一：

复制代码代码如下:

<?php

// Check whether the browser/gateway says it accepts WML.

$br = "WML";

} else {

$browser = isset($_SERVER['HTTP_USER_AGENT']) ? trim($_SERVER['HTTP_USER_AGENT']) : '';

if(empty($browser)) return true;

$mobile_os_list=array('Google Wireless Transcoder','Windows CE','WindowsCE','Symbian','Android','armv6l','armv5','Mobile','CentOS','mowser','AvantGo','Opera Mobi','J2ME/MIDP','Smartphone','Go.Web','Palm','iPAQ');

if($found_mobile)

else $br = "WWW";

}

return false;

}
