Kulinganisha timestamp na nyakati kwa kutumia PHP

Inawezekana kulinganisha tarehe, baada ya kuzibadilisha kuwa umbizo la timestamp. Tuangalie kwa mfano. Tuchukulie tuna tarehe mbili katika umbizo lifuatalo:

php<?php
  $date1 = ['2020', '12', '01'];
  $date2 = ['2019', '12', '31'];
?>

Wacha tubadilishe tarehe hizo kuwa umbizo la timestamp:

php<?php
  $time1 = mktime(0, 0, 0, $date1[1], $date1[0], $date1[2]);
  $time2 = mktime(0, 0, 0, $date2[1], $date2[0], $date2[2]);
?>

Wacha tulinganishe tarehe hizi:

php<?php
  var_dump($time1 > $time2);
?>

php$date1 = '2020-11-30';
$date2 = '2020-12-01';
