Description: ------------ PHP warnings WRT invalid arguments to foreach() are thrown when I access my mailbox using MailIMAPv2. Reproduce code: --------------- Line 1182 (in function _getDefaultPid) is as follows: foreach ($this->structure[$mid]['pid'] as $p => $id) { Expected result: ---------------- I've added if (is_array($this->structure[$mid]['pid'] { .. } around the aforementioned loop, and the warnings went away. Suggest inclusion in future releases of package. Actual result: -------------- I get numerous occurrences of the following (using my own error-logging method): Warning: Invalid argument supplied for foreach() in /usr/local/lib/php/Mail/IMAPv2.php on line 1182

Thanks for the bug report. I see the point of adding is_array(), but if $this->structure[$mid]['pid'] is not an array it's a sign of a larger problem. Can you tell me if there are anomolies in the message(s) being parsed that trigger this error? Do you get the expected output from that/those message(s)? Essentially, if $this->structure[$mid]['pid'] is not an array, there are no message parts, and message parsing has failed. I wouldn't expect a message with no parts. (no body, no attachments). That's why there is no check, it is essential to everything Mail_IMAP does that $this->structure[$mid]['pid'] be set an be an array. If you can reproduce the bug in a specific message, then send that message (in exactly the form you see it, not as an attachment to another message), to demo@smilingsouls.net. That is my live demo mailbox that houses unique messages that expose problems in Mail_IMAP's parsing algorithms, and also serves as quality assurance to test new releases of Mail_IMAP.

I will add some error reporting for this, BTW.

Message (w/ audio content) has generated by our system and sent to myself and demo@smilingsouls.net. Hope it contains helpful information. :)

Here's a dump of a partial context, as generated by my error handler. MailConnection is my own structure, encapsulating the Mail_IMAPv2 object (among other things).

Thanks, I don't see the message in the demo mailbox. http://www.smilingsouls.net/index.html?content=Mail_IMAP/live

I still do not have the test message. If you could try sending it again, that'd be grand. I'm adding an error for this for version 0.2.0.

Any news about this case? I still have this problem. Installed Versions: PHP 5.2.0 with Suhosin-Patch 0.9.6.1 (cli) Mail_IMAPv2, version 0.2.0
