note 130593 added to function.date-create-immutable

I like to use this function not only for creating a DateTimeImmutable object, but also to validate a date time string. <?php $a = isValidDateTimeString('21-07-1980'); $b = isValidDateTimeString('1985-05-20'); $c = isValidDateTimeString('2025-10-24 14:30:00'); $d = isValidDateTimeString('31.12.2000'); $e = isValidDateTimeString('10 September 2000'); $f = isValidDateTimeString('now'); $g = isValidDateTimeString('tomorrow'); var_dump($a, $b, $c, $d, $e, $f, $g); // all values are true function isValidDateTimeString(string $dateTimeString): bool { $dateTime = date_create_immutable($dateTimeString); return $dateTime instanceof DateTimeInterface; } ---- Server IP: 206.189.2.9 Probable Submitter: 2a02:a46d:5d5c:0:f44c:8030:200b:c019 ---- Manual Page -- https://php.net/manual/en/function.date-create-immutable.php Edit -- https://main.php.net/note/edit/130593 Del: integrated -- https://main.php.net/note/delete/130593/integrated Del: useless -- https://main.php.net/note/delete/130593/useless Del: bad code -- https://main.php.net/note/delete/130593/bad+code Del: spam -- https://main.php.net/note/delete/130593/spam Del: non-english -- https://main.php.net/note/delete/130593/non-english Del: in docs -- https://main.php.net/note/delete/130593/in+docs Del: other reasons-- https://main.php.net/note/delete/130593 Reject -- https://main.php.net/note/reject/130593 Search -- https://main.php.net/manage/user-notes.php
