W tej poradzie przedstawię kilka operacji na datach w formacie RRRR-MM-DD. Taki format może być np. pobierany z formularzy podczas podawania daty urodzenia.

Przykład:

Kod: php

<?php
$data_urodz = ‘1981-03-04′;
$data_obecna = date("Y-m-d");
$data_urodz_unix = strtotime($data_urodz);
$data_obecna_unix = strtotime($data_obecna);

$roznica_lata = ($data_obecna_unix - $data_urodz_unix) / (60*60*24*365.25);
$roznica_dni = ($data_obecna_unix - $data_urodz_unix) / (60*60*24);
$roznica_godziny = ($data_obecna_unix - $data_urodz_unix) / (60*60);
$roznica_minuty = ($data_obecna_unix - $data_urodz_unix) / (60);

echo "Minely ".$roznica_lata." lata od daty Twoich urodzin <br />";
echo "Minely ".$roznica_dni." dni od daty Twoich urodzin <br />";
echo "Minely ".$roznica_godziny." godziny od daty Twoich urodzin <br />";
echo "Minely ".$roznica_minuty." minuty od daty Twoich urodzin <br />";
?>

Pod zmienną $data_urodz możesz podstawić swoją datę urodzenia, a poznasz kilka ciekawych faktów.
