/*
Filter all fields and all rows in a recordset and returns the
processed recordset. We scroll to the beginning of the new recordset
after processing.
We pass a recordset and function name to RSFilter($rs,'rowfunc');
and the function will be called multiple times, once
for each row in the recordset. The function will be passed
an array containing one row repeatedly.
Example:
// ucwords() every element in the recordset
function do_ucwords(&$arr,$rs)
{
foreach($arr as $k => $v) {
$arr[$k] = ucwords($v);
}
}
$rs = RSFilter($rs,'do_ucwords');
*/

{
if ($rs->databaseType != 'array') {
if (!$rs->connection) return false;
$rs = $rs->connection->_rs2rs($rs);
}
$rows = $rs->RecordCount();
for ($i=0; $i < $rows; $i++) {
if (is_array ($fn)) {
$obj = $fn[0];
$method = $fn[1];
$obj->$method ($rs->_array[$i],$rs);
} else {
$fn($rs->_array[$i],$rs);
}
}
if (!$rs->EOF) {
$rs->_currentRow = 0;
$rs->fields = $rs->_array[0];

return $rs;
