我试图使用PHP代码填充组合框但不能正确执行/显示 登录界面的代码，从分支表中选择记录，并放入用户选择的组合按钮，但是没有正确显示，请检查 snapshot

根据目前的情况，我会说这是样式问题，似乎没有样式应用于您的选择标记。 （CSS）否则，它会在您的代码中显示它所在的位置。

修改

Chunk1：css非常小，头部内侧而不是链接

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
  <title>My first styled page</title>
  <style type="text/css">
  body {
    color: purple;
    background-color: #d8da3d }
  </style>
</head>

<body>
[etc.] (not shown)

与下一个2块组合（即chunk2和chunk3已经结婚）

Chunk2：外部css文件

这是首选方式，css是可重用的。 想象一下，这是一个名为myStyle.css的css文件

body {
  padding-left: 11em;
  font-family: Georgia, "Times New Roman",
        Times, serif;
  color: purple;
  background-color: #d8da3d }
ul.navbar {
  list-style-type: none;
  padding: 0;
  margin: 0;
  position: absolute;
  top: 2em;
  left: 1em;
  width: 9em }
h1 {
  font-family: Helvetica, Geneva, Arial,
        SunSans-Regular, sans-serif }
ul.navbar li {
  background: white;
  margin: 0.5em 0;
  padding: 0.3em;
  border-right: 1em solid black }
ul.navbar a {
  text-decoration: none }
a:link {
  color: blue }
a:visited {
  color: purple }
address {
  margin-top: 1em;
  padding-top: 1em;
  border-top: thin dotted }

Chunk3：包含我们刚刚在Chunk2中看到的myStyle.css

在<body>

中正确使用css样式 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
  <title>My first styled page</title>
  <link rel="stylesheet" href="myStyle.css">
</head>

<body>
[etc.] (not shown)

好的，结束了Chunks。你基本上需要这样做，因为通过PHP呈现的文本你没有做。再次注意，你要么做Chunk1，要么（Chunk2和Chunk3）。所以你的问题是造型/ html / css问题。
