.csv upload

I allow the user to map the fields in the csv file to my database fields, i then loop through the file and create a record for each record with eloquent. It takes quite a bit of time but want to use eloquent over directly importing via sql.

thoughts? suggestions?

while(! feof($file))
                {
                    $lead_value = fgetcsv($file);
                    $lead = new Lead();
                    $nullCount = 0;
                    $failBool = false;
                    foreach ($fields as $key => $field_value) {
                        //lead validation
                        if($request["$field_value"] != "null" ){
                            if(is_array($lead_value) && array_key_exists((int)$request["$field_value"], $lead_value)){
                                if($field_value == "billing_state" || $field_value == "phone"){
                                    if($field_value == "billing_state" && strlen($lead_value[(int)$request["$field_value"]]) >= 2) {
                                        $lead["$field_value"] = $this->setStateAbbr($lead_value[(int)$request["$field_value"]]);
                                    }
