[PHP] IMAP issues

I have just recently written a complete webmail software using PHP, and need to implement features that determin whether the email has been read or not. The function imap_setflag_full can set the flag, but i have no way of seeing which e-mails have what flags. imap_search allows you to search

[PHP] Regex nightmare:(

i need to uses reg ex to change to the < brackets have to be represented using < and > I have tried so many ways, but none work. here is an example of my faliure. $body = preg_replace("/(href=\/?)(\w+)(>\/?)/e","'\\1'.'\\2'./'target=_blank/ '.'\\3'", $body); Thanks
