How can PHP be used to dynamically handle an unknown number of textboxes in a form?

When dealing with an unknown number of textboxes in a form, we can use PHP to dynamically handle the input by iterating through the $_POST array. This allows us to process each textbox input without needing to know the exact number beforehand. We can use a loop to iterate through the array and handle each textbox value accordingly. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    foreach ($_POST as $key => $value) {
        // Handle each textbox input here
        echo "Textbox with name $key has value: $value <br>";
    }
}
?>
