如何在使用php生成的Excel单元格中添加新行

I have multiple address for a record and i want to add line break for each address with a cell named "Address". I tried adding " " AND PHP_EOL which didn't worked as desired.

Here is my code:

$indx = 1;
            $adr_data = "";
            foreach ($a_users_dtls as $ckt_dtls) {
                foreach ($ckt_dtls as $usr_dtls) {
                    $stat = '';
                    $header_row.= $indx++ . "\t" . $usr_dtls['name'] . "\t" . $usr_dtls['email_id'] ."\t".$usr_dtls['id'] ."\t" . $usr_dtls['cisdr'] . "\t" . $stat;
                    if ($showAddress1 == 1){
                        $address_list = explode("##,", $usr_dtls['address']); 
                        if(!empty($address_list)){
                            foreach($address_list as $key => $value){
                                $adr_data .=rtrim($value,',##')."
";
                            }
                        }
                        $header_row .= " \t ".$adr_data;
                    }
                    if ($showDisplayCity == 1)
                        $header_row .= " \t ".$usr_dtls['display_city'];
                    $header_row .= " 
 ";
                }
            }
            $filename = "user_list_" . date("Y_m_d") . "_" . time() . ".xls";
            header('Content-type: application/ms-excel');
            header('Content-Disposition: attachment; filename="' . $filename . '"');
            echo($header_row);
            exit;

When i try the above code i gets address in new rows of excel and not within the cell. I want to add line breaks within the cell named "Address" so that all address gets populated within a cell if there are multiple addresses.

Any help will be highly appreciated as i am new to excel generation via php.
