without the source code, we can not help.

You can only use it with a database object.

You can use this function for turning a normal array into csv:

function writeCSV($nome_do_arquivo, $array_de_arrays, $array_de_indices = array()) {

$arquivo = fopen(FCPATH.$nome_do_arquivo, 'w');

array_unshift($array_de_arrays, $array_de_indices);

foreach ($array_de_arrays as $array) {
fputcsv($arquivo, $array);
}

fclose($arquivo);

return readCSV($nome_do_arquivo, $array_de_indices);
}
