Question

所以我是php编程的新手，我试图用PHP编写一个简单的脚本来进行浏览器检测。一切对于'Chrome'和'Firefox'都可以正常工作，但是在使用'Edge'或'MSIE'浏览器时显示google'Chrome'的选项。

这里是代码，将非常感谢任何帮助。我的计算机默认浏览器是chrome，但是如果使用IE或Edge，它将显示Chrome的结果。我想念什么吗？

<html>
<body>
<form action="redirect.php" method = "post">
<!-- Centered and made heading size for the quick link announcement at top of page -->
<p><center><h2>Welcome to the quick link drop down menus for your browser.</h2> 
</center> 
</p>

<select name = "make">
<?php
    $user_agent = $_SERVER['HTTP_USER_AGENT'];
    if (preg_match('/MSIE/i', $user_agent))   // Internet Explorer
    {
    ?>
         <p>Here are Microsoft Internet Explorer links:</p>
         <!-- Add links for Microsoft internet explorer browser -->
