Edit report at https://bugs.php.net/bug.php?id=79442&edit=1 ID: 79442 Comment by: sjon@php.net Reported by: michael dot vorisek at email dot cz Summary: Nth day of month can not be set Status: Open Type: Bug Package: Date/time related PHP Version: 7.4.4 Block user comment: N Private report: N New Comment: what's wrong with two modify calls? It will allow you to do as many modifications as you want, I don't see how this qualifies as a bug. This works fine: $d = new \DateTime('2020-03-28 12:00:00'); echo $d ->modify('first day of -2 months') ->modify('+15 days') ->format('j.n.Y'); Previous Comments: ------------------------------------------------------------------------ [2020-04-01 07:38:07] michael dot vorisek at email dot cz Description: ------------ Is it currently possible to use multiple modifications to a date like "first day of -2 months, +15 days" in one modify() call? Is it currently possible to to write one modify for "15th day of -2 months"? Test script: --------------- $d = new \DateTime('2020-03-28 12:00:00'); // first day of the month, ok echo ((clone $d)->modify('last day of -2 months')->format('j.n.Y')) . "\n"; // 15th day of the month - not working echo ((clone $d)->modify('first day of -2 months, +15 days')->format('j.n.Y')) . "\n"; // bad result echo ((clone $d)->modify('15th day of -2 months')->format('j.n.Y')) . "\n"; // not parseable modify string Expected result: ---------------- 31.1.2020 15.1.2020 15.1.2020 Actual result: -------------- 31.1.2020 31.1.2020 Warning: DateTime::modify(): Failed to parse time string (15th day of -2 months) at position 0 (1) Fatal error: Uncaught Error: Call to a member function format() on bool ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79442&edit=1
