Get week number (in the year) from a date PHP
Today, using PHP's DateTime
objects is better:
<?php
$ddate = "2012-10-18";
$date = new DateTime($ddate);
$week = $date->format("W");
echo "Weeknummer: $week";
It's because in mktime()
, it goes like this:
mktime(hour, minute, second, month, day, year);
Hence, your order is wrong.
<?php
$ddate = "2012-10-18";
$duedt = explode("-", $ddate);
$date = mktime(0, 0, 0, $duedt[1], $duedt[2], $duedt[0]);
$week = (int)date('W', $date);
echo "Weeknummer: " . $week;
?>
Use PHP's date function
http://php.net/manual/en/function.date.php
date("W", $yourdate)
$date_string = "2012-10-18";
echo "Weeknummer: " . date("W", strtotime($date_string));
