What are the best practices for adapting complex email retrieval scripts found online to suit simpler requirements, such as displaying emails without user authentication?

To adapt complex email retrieval scripts found online to suit simpler requirements, such as displaying emails without user authentication, you can simplify the authentication process or remove it altogether. One way to achieve this is by directly accessing the email server using IMAP or POP3 protocols without requiring user credentials. This can be done by hardcoding the server details and credentials within the script, but be cautious about security implications. 

<?php
// Email server details
$server = '{mail.example.com:993/imap/ssl}INBOX';
$username = 'example@example.com';
$password = 'your_password';

// Connect to the IMAP server
$inbox = imap_open($server, $username, $password);

// Check if connection is successful
if ($inbox) {
    // Get emails
    $emails = imap_search($inbox, 'ALL');

    // Display emails
    if ($emails) {
        foreach ($emails as $email_number) {
            $email_header = imap_headerinfo($inbox, $email_number);
            echo "From: " . $email_header->fromaddress . "<br>";
            echo "Subject: " . $email_header->subject . "<br><br>";
        }
    } else {
        echo "No emails found.";
    }

    // Close the connection
    imap_close($inbox);
} else {
    echo "Failed to connect to the email server.";
}
?>
