Problem with imap_search

Hi,Sir: I try to count the result of imap_search as following example: ---------------------------------------- $c_num=imap_search($mbox,"SUBJECT ".$search_text); $total_num=count($c_num); echo $total_num; ---------------------------------------- I found that there is no keyword matched the mail SUBJECT , but it (the array numbers) appears that $totalnum =1 . --------------------------------------- Every time I try the same way, but It alwarys = 1 It should be 0 , shouldn't it ? Is there any body could tell me why? Thanks for any would reply me ....
