how to keep php output lines in one line

I just made a phone number to time zone converter and it displays result as:

Requested Phone No.: +1 732 78782722

Country: United States

Expected Region: Newark, New Brunswick

Timezone: America/New_York

Date: 2015-08-05

Time: 01:51:03 am

What I want to do is place all these outputs in a single line. Here's my output code

      if(!empty($record['country_name'])) {
            $this->display('<strong>Country:</strong> ' . $record['country_name']);
        }

        if(!empty($record['city'])) {
            $this->display('<strong>Expected Region:</strong> ' . $record['city']);
        }

        //echo json_encode($date); 

        if(!empty($record['zone_name'])) {
            $this->display('<strong>Timezone:</strong> ' . $record['zone_name']);
            $this->display('<h2><strong>Date:</strong> ' . date('Y-m-d') . '</h2>');
            $this->display('<h2><strong>Time:</strong> ' . date('H:i:s a') . '</h2>');
        }

Thanks for the help.
