How can PHP foreach loops be effectively utilized to process dynamic form input?

When dealing with dynamic form input, PHP foreach loops can be effectively utilized to iterate through the submitted data and process it accordingly. By using a foreach loop, you can easily loop through the array of form input values and perform actions such as validation, sanitization, or database insertion on each individual value. 

<?php
// Assuming form data is submitted via POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Iterate through each form input value using foreach loop
    foreach ($_POST as $key => $value) {
        // Process the form input value here (e.g. validate, sanitize, insert into database)
        echo "Key: " . $key . ", Value: " . $value . "<br>";
    }
}
?>
