Previous Comments: ------------------------------------------------------------------------ [2017-01-16 01:37:40] blindcan at gmail dot com Description: ------------ As the summary says, $date->modify('Friday this week') doesn't return a Friday if $date is a Sunday. Running the script below on 7.0.14 and 7.0.8 yields 2017-01-02, which is a Monday. However, running the same script on 7.0.5 yields 2017-01-13, a Friday. I expected a Friday. Test script: --------------- <?php $date1 = "2017-01-08"; // this is a Sunday $date = new \DateTime($date1); $date->modify('Friday this week'); $dateFormat = $date->format('Y-m-d'); echo $dateFormat; Expected result: ---------------- Currently, it displays a Monday date on 7.0.14. Testing on 7.0.8 also yields a Monday. I expect to see a Friday date on both PHP 7.0.5, and 7.0.14. Here's another link that tests for all php versions and other base days - https://3v4l.org/ZuOhl ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73942&edit=1
