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
control named "user" is submitted using the GET method, you can use
$_GET["user"] or $_GET['user']Example code
register.php:<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>
<?php
$username = $_POST['username'];
$name = $_POST['name'];
$pwd = $_POST['pwd'];
$email = $_POST['email'];
//print_r($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";
?>
