Json encode and Recordsets

Question

Hi,
I have a jquery autocomplete that requires a json response for a remote database. I am not familiar with json, so, I'm not sure if I'm using json_encode correctly.
The jquery script on my input page is straight from a working demo, so the problem seems to be with the json encode on the "search" php page.
This is from the Search.php page:
mysql_select_db($database_connmal, $connmal);
$query_rsname =
sprintf("SELECT act_info.first FROM act_info WHERE act_info.insight = %s
OR act_info.insight = 0", GetSQLValueString($colname_rsname, "int"));
$rsname = mysql_query($query_rsname, $connmal) or die(mysql_error());
$row_rsname = mysql_fetch_assoc($rsname);
$totalRows_rsname = mysql_num_rows($rsname);
echo json_encode($row_rsname);
Thanks,
Tim

The output on the search.php page is:
{"name":"name1"}
Only the first result shows from the recordset. I can echo everything in the recordset with:
do {
echo json_encode($row_Recordset1);
} while ($row_rsexercises = mysql_fetch_assoc($Recordset1));
but I don't think that's the right way to do it. It gives the following:
{"name":"name1"} {"name":"name2"} {"name":"name3"} {"name":"name4"}
Neither way is being picked up by the requesting page. Tried a couple of other things with no luck.
(Tested the input page by changing the url to the Jquery demo search.php page, that works fine.)
