How to receive form in php

php method of receiving the form

PHP can obtain the data submitted by the form through the POST and GET methods

The obtained POST and GET are values ​​in the form of arrays. You need to obtain the corresponding values ​​in detail through key values.

For example: index.php page

The following is the POST method

<form name="form1" method="post" action="index.php">
<input type="text" name="contents" value="">
<input type="submit" value="提交">
</form>
<?php
//获取表单提交的数据
$contents = $_POST[&#39;contents&#39;];
echo $contents;
?>

It can also be the GET method

<form name="form1" method="get" action="index.php">
<input type="text" name="contents" value="">
<input type="submit" value="提交">
</form>
<?php
//获取表单提交的数据
$contents = $_GET[&#39;contents&#39;];
echo $contents;
?>

Compared with the GET method, POST is better, can submit a large amount of data, and is more secure.
