Can you provide an example of using superglobal variables like $_POST to handle form data in PHP code?

When handling form data in PHP, you can use superglobal variables like $_POST to access the values submitted through a form. To process form data, you can check if the form has been submitted using the isset() function and then retrieve the values using $_POST['input_name']. This allows you to securely handle user input and perform actions based on the submitted data. 

<?php
if(isset($_POST['submit'])){
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Process the form data, for example, save it to a database
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <button type="submit" name="submit">Submit</button>
</form>
