【php】 检测 ie ie11 edge浏览器

Please note that Internet Explorer 11 no longer contains MSIE in its user agent string, for example on Windows 8 with IE11 I get the following:

Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; rv:11.0) like Gecko

So if you want to include a test for IE11, the code above changes to: 

<?php
if (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== FALSE ||
    strpos($_SERVER['HTTP_USER_AGENT'], 'Trident') !== FALSE) {
    echo 'You are using Internet Explorer.<br />';
}
?>

On Edge, the user agent string does not contain 'MSIE' neither 'Trident', but rather 'Edge'.

 

建议使用者亲测，我自测结果和上述有点不一样，因为WIN7电脑不能安装EDGE，所以我是用调试平台调试的，具体情形需浏览人员自行甄别
