The imap_num_recent function returns the number of recent messages in the current
mailbox.
<?
$mailbox = imap_open("{mail.server.com}INBOX",
"leon", "password");
print("Number of Messages: ".
imap_num_msg($mailbox));
imap_close($mailbox);
?>
integer imap_open(string mailbox, string username, string
password, integer flags)
Use imap_open to begin a connection to a mail server. The mailbox argument is
usually formed by adding a hostname to the beginning of the mailbox. The hostname is
enclosed in curly braces. Adding /pop3 causes the imap_open function to connect to
a POP server instead of an IMAP server. Adding /nntp allows you to connect to a
usenet server. You may also specify a port number, using a colon to separate it from the
hostname. A stream identifier is returned. Use this identifier with the IMAP functions
that require a stream. The optional flags argument is a bitfield that uses the constants
listed in Table 14.8.
