Summary of PHP get form method
When PHP accepts information submitted through an HTML form, it will save the submitted data in a 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 "txtAge" is submitted using the GET method, you can use
$_GET["txtAge"] or $_GET['txtAge']
Get the value it submitted.

$_REQUEST automatic global variable contains all GET, POST, COOKIE and FILE data. If you don’t care about the data source, you can use

$_REQUEST["txtAge"] or $_REQUEST['txtAge'] to get the submitted data.

The following is a simple example of obtaining submitted data:

<?php

echo("你的帐号是：" . $_POST['login']);   //输出帐号
echo("<br>");
echo("你的姓名是：" .$_POST['yourname'] );   //输出姓名
echo( "<br>");

echo("你的密码是：" . $_POST['passwd']   );   //输出密码
echo("<br>");

echo("你的查询密码问题是：" . $_POST['question']   );   //查询密码问题
echo("<br>");

echo("你的查询密码答案是：" . $_POST['question2']    );   //查询密码答案
echo("<br>");

echo("你的出生日期是：" . $_POST['byear'] ."年". $_POST['bmonth'] . "月" . $_POST['bday'] 
. "日"    );   //出生日期
echo("<br>");


echo("你的性别是：" . $_POST['gender']);   //性别
echo("<br>");


echo("你的爱好是：<br>"   );   //爱好
foreach ($_POST['hobby'] as $hobby) {
   echo($hobby . "<br>");
}

?>
