This section will provide a comprehensive example, which will integrate various components related to the form introduced in the previous chapter examples to achieve a comprehensive application of all components together. Mainly based on the "Inserting a form into an ordinary WEB page" in the previous chapter, PHP code is used to obtain the value of the form element. Submit the values of each component to this page through the POST() method, and obtain the submitted values through $_POST.

The specific operation steps are as follows:

<form action="index.php" method="post" name="form1" enctype="multipart/form-data">
  <table width="400" border="1" cellpadding="1"  bgcolor="#999999">
    <tr bgcolor="#FFCC33">
      <td width="103" height="25" align="right">姓名：</td>
      <td height="25">

      </td>
    </tr>
