How can PHP be utilized to enhance the security of email addresses stored in a mailing list?

Email addresses stored in a mailing list are often vulnerable to security breaches if they are stored in plain text. To enhance security, PHP can be utilized to encrypt or hash the email addresses before storing them in the database. This way, even if the database is compromised, the email addresses will not be easily readable. 

// Encrypt or hash email addresses before storing them in the database
$encrypted_email = password_hash($email, PASSWORD_DEFAULT);

// Store the encrypted email address in the database
// INSERT INTO mailing_list (email) VALUES ('$encrypted_email');
