In PHP, the predefined $_POST variable is used to collect values from the form with method="post". Below I will bring you an example of PHP using super global variable $_POST to receive form data. The following is the code:

<!doctype html>
<html>
<head>
<title>利用超级全局变量$_POST接收表单</title>
<meta http-equiv="content-type" contnet="text/html" charset="utf-8"/>
</head>
<body>
<form method="post" action="<?php echo $_SERVER[&#39;PHP_SELF&#39;];?>"/>
Name:<input type="text" name="fname"/>
<input type="submit"/>
</form>
<?php
$name= $_POST[&#39;fname&#39;];
echo $name;
?>
</body>
</html>

The output content uses the post method to submit the data, and then uses $_POST['fname']; to receive the data and assign it to the global variable of $name,

Then use echo to output $name; the variable gets the final result, which is the content in the form. .............
