PHP code to demonstrate the example of $_REQUEST superglobal variable

The source code to demonstrate the use of the $_REQUEST superglobal variable is given below. The given program is compiled and executed successfully.

<html>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
  Enter country name: <input type="text" name="country">

//superglobal variable.
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
    $country = htmlspecialchars($_REQUEST['country']);
    printf("Country Name: %s<br>", $country);
}
?>

</body>
</html>

Output

o/p

Explanation

In the above program, we create a form tag with the post method that contains an input field and a submit button.

if ($_SERVER["REQUEST_METHOD"] == "POST") 
{
    $country = htmlspecialchars($_REQUEST['country']);
    printf("Country Name: %s<br>",$country);
}

Here, we checked the request method using $_SERVER superglobal, then we get the value of the input field using $_REQUEST superglobal and then printed the country name using printf() function on the webpage.
