Prefix the function in question with a '@', e.g. @imap_header() .

Hi,

I am already using the function as

##############
for ($i = $begin, $j = $beginIndex; $i <= $end; $i++, $j++) {
$msgnum = $sorted[$i-1];
$h = @imap_header($imp->stream, imap_msgno($imp->stream, $msgnum));
... and further
}
##############

But for a mail message that is sent without any TO and only BCC, the function returns a warning (as already shown in the message placed initially) because such mails have TO field as
To: <Undisclosed-Recipient:;@vd1.vsnl.net.in;>

And the function is not able to handle it.
Please suggest what to do to overcome this.

To get this error, jsut send a mail to some account with email-address in BCC field only and then see mails using some IMAP web interface.

Thanks

Achso, ic. Well, this comes from the imap library itself, there's nothing you can do about; complain to the imap developers. You can, however, patch around it yourself if you're feeling brave (and know what you're doing).

Then can you please tell me how to do the required settings to compress any warning from getting displayed.

For your reference, in the horde-imp script, i had already tried by making changes as below. But can i do that somehow by some server settings..!!

1. In the file /lib/imp.lib
var $error_level = E_ALL
changed to
var $error_level = 0;    

2. In the /config/defaults.php3.dist
$default->error_level = E_ALL;
changed to
$default->error_level = 0;

Should i expect any feedback from you now ..
I had crosschecked everything with IMAP guys and here is what they said in reply to my questions..

There is no such function in the c-client library.  That must be a PHP function.
I don't know if PHP is calling any c-client imap_???() functions directly, but if it is, then it is very broken.  All c-client imap_???() functions are internal to c-client and must not be calle dexternally.


> Otherwise, is there any work around to atleast stop warning to appear!!
It all depends upon what is displaying those warnings.
c-client displays nothing.  The display is being done by something outside of c-client, and c-client gave it the information to know what type of event it was.
If your application is displaying mm_log() events with no way to suppress them even if errflg=3, then this is a bug in your application and it's your bug to fix.
If PHP is displaying mm_log() events with no way to suppress them even if errflg=3, then this is a bug in PHP and it's the PHP maintainers' bug to fix.

Well, look at the code yourself.  This error message comes from the imap libraries and not from PHP.  It is displayed by PHP through the mm_log() callback which is wrapped like this:
void mm_log(char *str, long errflg)
{
    ERRORLIST *cur = NIL;
    TSRMLS_FETCH();

    if (!(EG(error_reporting) & E_NOTICE)) {
        return;

ie. it will only display if E_NOTICE is turned on.  So PHP is correct in that it only optionally displays these.  You must not have turned E_NOTICE off correctly.
