note 127370 added to class.datetime

PHP objects can be compared and you can use this with DateTime. An anonymous person posted a note about the comparisons returning FALSE on the first unequal property found (https://www.php.net/manual/en/language.oop5.object-comparison.php#98725), but it does not seem to affect DateTime objects when comparing dates with different timezones - at least in the PHP version I used (8.0.13). <?php // Same timezone. $a = new DateTime("2022-07-30 12:30:00+0300"); $b = new DateTime("2022-07-30 12:30:00+0300"); $c = new DateTime("2022-07-15 12:30:00+0300"); var_dump($a == $b); // True. var_dump($a > $b); // False. var_dump($a < $b); // False. var_dump($a > $c); // True. // Different timezones. $c = new DateTime("2022-07-12 12:30:00+0300"); $d = new DateTime("2022-07-12 12:30:00+0000"); $f = new DateTime("2022-07-12 09:30:00+0000"); var_dump($c < $d); // True. var_dump($c == $d); // False. var_dump($c > $d); // False. var_dump($c == $f); // True. ?> ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.135 (proxied: 185.101.176.229) ---- Manual Page -- https://php.net/manual/en/class.datetime.php Edit -- https://main.php.net/note/edit/127370 Del: integrated -- https://main.php.net/note/delete/127370/integrated Del: useless -- https://main.php.net/note/delete/127370/useless Del: bad code -- https://main.php.net/note/delete/127370/bad+code Del: spam -- https://main.php.net/note/delete/127370/spam Del: non-english -- https://main.php.net/note/delete/127370/non-english Del: in docs -- https://main.php.net/note/delete/127370/in+docs Del: other reasons-- https://main.php.net/note/delete/127370 Reject -- https://main.php.net/note/reject/127370 Search -- https://main.php.net/manage/user-notes.php
