Text Data Storage - Part 1: Data storage alternative which we have learned is use the CSV. CSV can be classified as plain text. But sometimes we require the special format. We can make it own use the custom text file.

For this job, we can use fprint. We have learned at here about fprint().

Example:

<?
$dat = fopen('test.dat', 'w');
$year = 2008;
$month= 2;
$day = 5;
$code = 'BXD';
$property = 'Notebook';
$price = '1990.39';

// first line
fprintf($dat, "%04d-%02d-%02d\n", $year, $month, $day);

// second line
fprintf($dat, "%3s*%-40s %f\n", $code, $property, $price);

fclose($dat);
?>
