When

php accepts information submitted through the HTML form, it will save the submitted data in the global array. We can call the system-specific automatic global variable array to obtain these values. . Commonly used automatic global variables are as follows:

$_GET
$_POST
##$ _REQUEST

In obtaining form data, the most commonly used automatic global variables are $_GET and $_POST, which obtain data submitted through the GET method and data submitted through the POST method respectively. For example, if a text box form

control named "user" is submitted using the GET method, you can use

$_GET["user"] or $_GET['user']

Example code

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html;charset=gb2312"> 
<title>注册页面</title> 
</head> 
<body> 
<form action="request.php" method="post" name="registForm"> 
<table width="330" border="0" align="center" cellpadding="5" bgcolor="#eeeeee"> 
<tr> 
<td width="40%">用户名:</td> 
<td><input name="username" type="text" id="username"/></td> 
</tr> 
<tr> 
<td>姓名:</td> 
<td><input name="name" type="text" id="name"/></td> 
</tr> 
<tr> 
<td>密码:</td> 
<td><input name="pwd" type="text" id="pwd"/></td> 
</tr> 
<tr> 
<td>邮箱:</td> 
<td><input name="email" type="text" id="email"/></td> 
</tr> 
<tr> 
<td colspan="2" align="center"> 
<input type="submit" value="提交" name="submit"/> 
<input type="reset" value="重置" name="button"/> 
</td> 
</tr> 
</table> 
</form> 
</body> 
</html>

request.php

<?php 
$username = $_POST[&#39;username&#39;]; 
$name = $_POST[&#39;name&#39;]; 
$pwd = $_POST[&#39;pwd&#39;]; 
$email = $_POST[&#39;email&#39;]; 
//print_r($username); 
if(!empty($username)) 
{ 
echo "您填写的信息为：<br>\n"; 
echo "用户名: $username <br>\n"; 
echo "姓名： $name <br>\n"; 
echo "密码: $pwd <br>\n"; 
echo "邮箱: $email <br>\n"; 
} 
print_r($_POST) 
//echo "aaaa";
