[PHP][討論] PHP函數問題
有一段程式碼看唔明,請教各位高手,紅色那個函數是咩意思呢?
$query=$db->query("SELECT t.tid,t.postdate,tm.aid,t.author,t.subject,t.replies,t.ifupload,t.pollid FROM pw_threads t LEFT JOIN pw_tmsgs tm ON tm.tid=t.tid WHERE t.tid IN($delids)"); while(@extract($db->fetch_array($query))){ if($aid){ $attachs= unserialize(stripslashes($aid)); foreach($attachs as $key=>$value){ is_numeric($key) && $delaids.=$key.',' } }
另外, dtchange($author,-$db_dtdelrvrc,"-1",-$db_dtdelmoney);
dtchane這個函數是咩意思呢?
