[BUG] Fatal error: Uncaught ValueError: IMAP\Connection is already closed

[eddi13]

• PHP IMAP version: 5.0.0
• PHP Version: 8.1.10

PHP Fatal error: Uncaught ValueError: IMAP\Connection is already closed in .../PhpImap/Mailbox.php:479 Stack trace: #0 .../PhpImap/Mailbox.php(479): imap_ping() #1 .../PhpImap/Mailbox.php(544): PhpImap\Mailbox->hasImapStream() #2 .../PhpImap/Mailbox.php(187): PhpImap\Mailbox->disconnect()

I'm getting the same since the upgrade to PHP 8.1.11

Probably because of this: https://www.php.net/ChangeLog-8.php

Version 8.1.10

IMAP: Fixed bug GH-9309 (Segfault when connection is used after imap_close()).

[ghnp5]

To me, this happens because I'm calling unset($mailbox) which calls $mailbox->destruct() which will try to close the IMAP connection which I've already closed by invoking $mailbox->disconnect().

I can confirm this happens also with version 8.1.13.

Should be fixed in version 5.0.1.

And what about: public static function ping($imap_stream): bool in Imap class?
