From: romash1408 at yandex dot ru Operating system: UNIX PHP version: 7.3.5 Package: Date/time related Bug Type: Bug Bug description:strtotime('last <day of week> + 7 days') incorrect result Description: ------------ Today is 2019-05-29, wednesday. In any php 7.* interpreter I write echo date('Y-m-d', strtotime('last wednesday')); and get last week's day (2019-05-22) echo date('Y-m-d', strtotime('last wednesday + 1 day')); shows correct date too (2019-05-23) But echo date('Y-m-d', strtotime('last wednesday + 7 day')); gives result like 'last wednesday' was today (2019-06-05) Live example on Ideone: https://ideone.com/1YzDpS php 5.6 doesn't have this bug! Test script: --------------- $day = date("l"); echo date("Y-m-d", strtotime("last $day")) . "\n"; echo date("Y-m-d", strtotime("last $day + 1 day")) . "\n"; echo date("Y-m-d", strtotime("last $day + 6 day")) . "\n"; echo date("Y-m-d", strtotime("last $day + 7 day")) . "\n"; Expected result: ---------------- 2019-05-21 2019-05-22 2019-05-27 2019-05-28 Actual result: -------------- 2019-05-21 2019-05-22 2019-05-27 2019-06-04 -- Edit bug report at https://bugs.php.net/bug.php?id=78080&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=78080&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=78080&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=78080&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=78080&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78080&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78080&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78080&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78080&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78080&r=support Expected behavior: https://bugs.php.net/fix.php?id=78080&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78080&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78080&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78080&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=78080&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=78080&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78080&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78080&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78080&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78080&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78080&r=mysqlcfg
