我用dreamweaver做了个页面,想在其中的文本框内显示地址上指定路径的文本文件,请问下该怎么添加修改PHP语句。
页面源代码如下:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>Examine Rule</title>
</head>

<body> 

<h1 align="center">Display Rule</h1>
<div align="center">
  <table width="426" height="300" border="1">
    <tr>
      <td height="34" colspan="2"> <div align="center">choose rules</div>
        <form name="form2" method="post" action="">
          <div align="center">Location:
            <input name="textfield" type="text" size="60">
          </div>
        </form> </td>
    </tr>
    <tr>
      <td height="213" colspan="2"><p align="center">IDS Rules:</p>
        <form name="form1" method="post" action="">
          <div align="center">
            <textarea name="textarea" cols="80" rows="10"></textarea>
   </div>
      </form>        </td>
    </tr>
    <tr>
      <td width="277" height="25"><form name="form3" method="post" action="">
        <div align="center">
          <input type="submit" name="Submit" value="Display">
        </div>
      </form></td>
      <td width="290"><form name="form4" method="post" action="">
        <div align="center">
          <input type="button" class="button1" onclick="document.location.href='../snort/index.php'" value="Return">
        </div>
      </form></td>
    </tr>
  </table>
</div>
<p align="center"> </p>
</body>
</html> 

    <p>
      <input type="submit" name="Submit" value="OpenFileCatalog">
    </p>
  </div>
</form>
<p align="center">  </p>
</body>
</html>
