If you do not use imap_errors() to clear the error stack, any errors that remain at the end of the script execution will be raised as PHP Notices.

imap_errors — Devuelve todos los errores IMAP ocurridos
Esta función devuelve un array de todos los mensajes de error IMAP generados desde la última llamada a imap_errors() o desde el inicio de la página.
Cuando imap_errors() es llamada, la pila de errores es vaciada.
Esta función no contiene ningún parámetro.

If you do not use imap_errors() to clear the error stack, any errors that remain at the end of the script execution will be raised as PHP Notices.For those curious, this function will return a linear array of strings as opposed to say error_get_last which returns an associative array of different things.
e.g.
[0 => '[TRYCREATE] No folder {imap.gmail.com} (Failure)']This can generate the string "Mailbox is empty" right after a call to imap_open(). That's not an error. That means something like this is not good enough to know the open failed due to a wrong password or host name or whatever. This
$imap = @imap_open( $mailbox, $user, $pass);
$errors = @imap_errors();
if ( $errors ) {
echo 'Login failed: ' . implode ('; ', $errors );
}
can output "Login failed: Mailbox is empty" which is silly.
Instead, check the return value from imap_open().
$imap = @imap_open( $mailbox, $user, $pass);
if ( ! $imap ) {
$errors = @imap_errors();
echo 'Login failed: ' . implode ('; ', $errors );
}When calling imap_close($mbox), notices will be generated for each error that has occurred within the imap functions. To suppress these error messages (including Mailbox is empty, which is not really an error) simply call imap_errors() and then imap_close($mbox).
