Are there any best practices for managing IMAP connections in PHP applications?

When working with IMAP connections in PHP applications, it's important to properly manage connections to avoid memory leaks and performance issues. One best practice is to always close the IMAP connection after you're done using it. This ensures that resources are released and the connection is properly terminated.

// Open IMAP connection
$imap = imap_open('{imap.example.com:993/imap/ssl}INBOX', 'username', 'password');

// Do some operations with the IMAP connection

// Close the IMAP connection
imap_close($imap);
