note 107606 added to function.date

I use the function below to calculate the Unix timestamp of the start of a week. It includes a boolean flag to request a GMT offset instead of the current locale setting. <?php function getWeekOffsetTimestamp($year, $week, $useGmt = false) { if ($useGmt) { // Backup timezone and set to GMT $timezoneSettingBackup = date_default_timezone_get(); date_default_timezone_set("GMT"); } // According to ISO-8601, January 4th is always in week 1 $halfwayTheWeek = strtotime($year."0104 +".($week - 1)." weeks"); // Subtract days to Monday $dayOfTheWeek = date("N", $halfwayTheWeek); $daysToSubtract = $dayOfTheWeek - 1; // Calculate the week's timestamp $unixTimestamp = strtotime("-$daysToSubtract day", $halfwayTheWeek); if ($useGmt) { // Reset timezone to backup date_default_timezone_set($timezoneSettingBackup); } return $unixTimestamp; } ?> ---- Server IP: 91.199.167.223 Probable Submitter: 80.57.149.71 ---- Manual Page -- http://www.php.net/manual/en/function.date.php Edit -- https://master.php.net/note/edit/107606 Del: integrated -- https://master.php.net/note/delete/107606/integrated Del: useless -- https://master.php.net/note/delete/107606/useless Del: bad code -- https://master.php.net/note/delete/107606/bad+code Del: spam -- https://master.php.net/note/delete/107606/spam Del: non-english -- https://master.php.net/note/delete/107606/non-english Del: in docs -- https://master.php.net/note/delete/107606/in+docs Del: other reasons-- https://master.php.net/note/delete/107606 Reject -- https://master.php.net/note/reject/107606 Search -- https://master.php.net/manage/user-notes.php
