How can the user iterate through the array of messages returned by the PHP function for output?

To iterate through the array of messages returned by the PHP function for output, you can use a foreach loop. This loop will allow you to access each message in the array and output it as needed. By using this loop, you can ensure that all messages are displayed to the user.

// Assume $messages is the array of messages returned by the PHP function

foreach ($messages as $message) {
    echo $message . "<br>";
}
