What are the limitations of using imap functions in PHP when working with POP3 mailboxes?

When working with POP3 mailboxes, using IMAP functions in PHP may not work as expected due to the differences in protocols. To overcome this limitation, you can use a PHP library like `php-POP3` that specifically handles POP3 connections and operations. 

// Example of using php-POP3 library to work with POP3 mailboxes
require_once 'pop3.php';

$pop3 = new POP3('pop3.example.com', 110);
$pop3->connect('username', 'password');

// Retrieve emails
$emails = $pop3->getMessages();

// Process emails
foreach ($emails as $email) {
    echo $email['headers'] . "\n";
    echo $email['body'] . "\n";
}

$pop3->disconnect();
