I am having a tough time to do this...

I have created two table say table-1 and table-2 in same database.what I want is I need to copy some values from table-1 and insert the same to table-2. I have tried many ways but it does not seems work. below is my code can any one tell me where I am missing??

 $db = mysql_connect("localhost", "user", "pass") or die("Could not connect.");
    mysql_select_db("comdata",$db)or die(mysql_error()); 
    $resultb = mysql_query("SELECT * FROM table-2")or die(mysql_error()); 
    $row = mysql_fetch_array($resultb);
    $days = (strtotime(date("Y-m-d")) - strtotime($row['regtime'])) / (60 * 60 * 24);
    if($row > 0 && $days < 1){
       $person = $row['person'];
       $catogr = $row['catog'];
       $position = $row['position'];
       $location = $row['location'];
       $rank = $row['rank'];
    mysql_close($db);
    }else{
    $db = mysql_connect("localhost", "user", "pass") or die("Could not connect.");
    mysql_select_db("comdata",$db)or die(mysql_error());  
    $result = mysql_query("SELECT * FROM table-1 WHERE regtime = DATE(NOW()) ORDER BY rank ASC LIMIT 1;")or die(mysql_error());
    $row = mysql_fetch_array($result);
       $person = $row['person'];
       $catogr = $row['catog'];
       $position = $row['position'];
       $location = $row['location'];
       $rank = $row['rank'];
 mysql_query("INSERT INTO table-2 
    (regtime,person,catog,position,location,rank)  VALUES(NOW(),'$person','$catogr','$position','$location','$rank')");
    mysql_close($db);
        }
