What is the significance of using $key and $value in a foreach loop when handling form data in PHP?

When handling form data in PHP, using $key and $value in a foreach loop allows you to easily access and process each form input field. $key represents the name of the form input field, while $value represents the value entered by the user. This approach simplifies the process of iterating through form data and performing actions based on the input fields. 

// Example of using $key and $value in a foreach loop to handle form data
foreach ($_POST as $key => $value) {
    // Process each form input field
    echo "Field name: " . $key . "<br>";
    echo "Value entered: " . $value . "<br>";
}
