New Line

To create a second row in a spreadsheet a new line is required. The only way I can get a new line is by echo PHP_EOL. The script shown below creates two lines when viewed in a text editor and two rows when viewed in a spreadsheet programme.

  <?php
  header('content-type: text/csv');
  header('content-disposition: attachment;filename=ticket-sales.csv');
  echo "a, b, c, d, e";
  echo PHP_EOL;
  echo "f, g, h, i, j";
