How can dynamic field detection be implemented in PHP to avoid manual adjustments in code?

Dynamic field detection in PHP can be implemented using the `$_POST` superglobal array to automatically detect and handle form fields without needing manual adjustments in the code. By looping through the `$_POST` array, you can dynamically process form data regardless of the number of fields submitted.

foreach ($_POST as $key => $value) {
    // Process each form field dynamically
    echo "Field: $key, Value: $value <br>";
}
