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>
