Things to be aware of when using week numbers with years.
<?php
echo date("YW", strtotime("2011-01-07")); // gives 201101
echo date("YW", strtotime("2011-12-31")); // gives 201152
echo date("YW", strtotime("2011-01-01")); // gives 201152 too
?>
BUT
<?php
echo date("oW", strtotime("2011-01-07")); // gives 201101
echo date("oW", strtotime("2011-12-31")); // gives 201152
echo date("oW", strtotime("2011-01-01")); // gives 201052 (Year is different than previous example)
?>
Reason:
Y is year from the date
o is ISO-8601 year number
W is ISO-8601 week number of year
Conclusion:
if using 'W' for the week number use 'o' for the year.week starting date and end date in php
<?php
$week=29;
$year=2017;
function getStartAndEndDate($week, $year)
{
$dateTime = new DateTime();
$dateTime->setISODate($year, $week);
$result['start_date'] = $dateTime->format('d-M-Y');
$dateTime->modify('+6 days');
$result['end_date'] = $dateTime->format('d-M-Y');
return $result;
}
$dates=getStartAndEndDate($week,$year);
print_r($dates);
