Is there a way to select a single column from a mysql database and
directly put the results into an arrray? Here is the workaround below,
but I would like to elimniate the array_push step:
$uids=array();
$res = mysql_db_query("db", 'select uid from tbl;', $link);
while ($row = mysql_fetch_row($res)) {
array_push ($uids, $row[0]);
