How can PHP arrays be utilized to simplify the handling of dynamic form fields?

When dealing with dynamic form fields, it can be challenging to handle the data efficiently as the number of fields may vary. One way to simplify this process is by using PHP arrays to store the form field values. By dynamically adding form field values to an array, you can easily iterate through them and process the data without needing to know the exact number of fields beforehand. 

// Sample code to handle dynamic form fields using PHP arrays
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $dynamicFields = [];
    
    // Loop through POST data to extract dynamic form field values
    foreach ($_POST as $key => $value) {
        if (strpos($key, 'dynamic_field_') === 0) {
            $dynamicFields[$key] = $value;
        }
    }
    
    // Process the dynamic form field values stored in the array
    foreach ($dynamicFields as $key => $value) {
        echo "Field name: $key, Field value: $value <br>";
    }
}
