its easy i think
you should make two db handlers
PHP Code:
//your primary connection
$conn = mysql_connect("host1","username","password");
if($conn){
//connect to your first db with first handle
mysql_select_db('database1', $conn);
$conn2 = mysql_connect("host1","username","password",true);
//should put that true to make a new connection
//connect to your second db with 2nd handle
mysql_select_db('database2', $conn2);
{
you can make with the same handle as well
and dont use the MAKE connection thing inside a loop
unless it will make multiple connections
if you have no option, use mysql_pconenct
but if you put your code, i can tell you better
