How can PHP arrays be effectively utilized to store and retrieve form data in a loop?

When dealing with form data in a loop, PHP arrays can be effectively utilized to store and retrieve the data for each iteration. By creating an array to hold the form data, you can easily access and manipulate the values within the loop. This allows for a more organized and efficient way to handle form submissions and processing. 

// Initialize an empty array to store form data
$form_data = array();

// Loop through the form data and store it in the array
foreach ($_POST as $key => $value) {
    $form_data[$key] = $value;
}

// Retrieve and display the form data stored in the array
foreach ($form_data as $key => $value) {
    echo $key . ': ' . $value . '<br>';
}
