[PHP] PHP vs Algorithm

[Firman Wandayandi]

Hi All,

I want to make algorithm representation of my code for my homework, but I have no idea 
to convert PHP code to algorithm. Can anyone help me?

Code:

--- begin code ---

function doAdd($command, $options, $params) {
        $kategori = new Silaris_Kategori($params);
        $res = $kategori->saveKategori();
        if (Silaris::isError($res)) return $res;
        if (!empty($kategori->errors)) {
            $messages = array();
            foreach ($kategori->errors as $field => $msg) {
                $messages[$field] = '['. ucfirst($msg) . ']';
            }

            $dlgdata = $this->_getDialogData($kategori, $messages);
            if (Silaris::isError($dlgdata)) return $dlgdata;
            $this->ui->outputData($dlgdata, 'kat-showadd');
            return false;
        }
        return true;
    }

--- end code ----

Algorithm:
