NuSOAP & returning Arrays...

Right now I am dealing with some strange behavior when returning arrays. I have a function registered with a NuSOAP server that essentially creates an array as follows based on results of a MySQL DB query: function buildresultstable($res){ if ($res == null) return null; $num_rows = mysql_num_rows($res); $table = array(); for ($i = 0; $i < $num_rows; $i++){ $table[$i] = mysql_fetch_assoc($res); } return $table; } However, when I receive this array on the other side, NuSOAP appears to have added an outer array containing only the above table, meaning I have to remember to use $res[0][rownum]["fieldname"] to access the data. Is there a reason for this, and is there a way to prevent this extra outer array from being created -- requiring the extra "[0]" kinda irritating? This does not, incidentally, occur when I am returning a one dimensional associative array, but I imagine that may be because it doesn't appear to treat them as arrays when generating the SOAP message.
