问题描述
I have created two simple web pages, one is written in HTML, and the second is written in PHP. 
我已经创建了两个简单的网页，一个用HTML编写，第二个用PHP编写。 In the HTML page, I include form tag with action attribute and its attribute value is index.php(second page) and index.php(second page) include $_REQUEST but no value is displayed. 在HTML页面中，我包含带有动作属性的表单标记，其属性值是index.php（第二页），而index.php（第二页）包括$ _REQUEST，但不显示任何值。
html page HTML页面
<html>
<head>
<title>testing of php</title>

<body>
<h3>here the value will be displayed</h3>
<form method="post" action="index.php">
please enter your name:
<input type="text" name="don"></input><br>
<input type="button" value="send"></input>
</form></body>
</html>
