Why is it important to access the original key in $_POST when looping through the values?

When looping through the values of $_POST, it is important to access the original key in order to properly handle and process the form data. This is because the keys in $_POST correspond to the form field names, which are essential for identifying and working with the submitted data. By accessing the original key, you can accurately retrieve and manipulate the values associated with each form field. 

foreach ($_POST as $key => $value) {
    // Access the original key to work with form field names
    echo "Field name: " . $key . ", Value: " . $value . "<br>";
}
