It seems that the safest way to check for errors is not by checking the number of errors, but warnings instead. See the following example where "m" and "d" are swapped and thus not correct. <?php var_dump( date_parse_from_format('m.d.Y', '18.10.2024') ); OUTPUT: array(12) { ["year"]=> int(2024) ["month"]=> int(18) ["day"]=> int(10) ["hour"]=> bool(false) ["minute"]=> bool(false) ["second"]=> bool(false) ["fraction"]=> bool(false) ["warning_count"]=> int(1) ["warnings"]=> array(1) { [10]=> string(27) "The parsed date was invalid" } ["error_count"]=> int(0) ["errors"]=> array(0) { } ["is_localtime"]=> bool(false) } ?> The function simply assigns 18 to the "month" field without errors!! So simply use an if-condition and check "warning_count" to detect possible errors. ---- Server IP: 45.112.84.4 Probable Submitter: 80.90.5.137 (proxied: 147.161.255.73) ---- Manual Page -- https://php.net/manual/en/function.date-parse-from-format.php Edit -- https://main.php.net/note/edit/129810 Del: integrated -- https://main.php.net/note/delete/129810/integrated Del: useless -- https://main.php.net/note/delete/129810/useless Del: bad code -- https://main.php.net/note/delete/129810/bad+code Del: spam -- https://main.php.net/note/delete/129810/spam Del: non-english -- https://main.php.net/note/delete/129810/non-english Del: in docs -- https://main.php.net/note/delete/129810/in+docs Del: other reasons-- https://main.php.net/note/delete/129810 Reject -- https://main.php.net/note/reject/129810 Search -- https://main.php.net/manage/user-notes.php
