Bug #75992 [NEW]: DateTime::createFromString() does not work with years > 4 digits

From: dktapps at pmmp dot io Operating system: Windows 10 PHP version: 7.2.2 Package: Date/time related Bug Type: Bug Bug description:DateTime::createFromString() does not work with years > 4 digits Description: ------------ DateTime formats can be created using format() which have >4 digits in the year, which cannot be parsed using createFromFormat() with the same format-string. As seen below the same format is used both times. This bug report looks absurd, but I've had similar issues been auto-reported to my crash archive when users put absurd values in configuration, and this appears to be why. Test script: --------------- <?php $datetime = new \DateTime('@' . PHP_INT_MAX); $str = $datetime->format("Y-m-d H:i:s O"); var_dump($str); //275808-11-04 10:06:43 +0000 var_dump(\DateTime::createFromFormat("Y-m-d H:i:s O", $str)); //bool(false) ?> Expected result: ---------------- Either: bool(false) bool(false) OR string(33) "292277026596-12-04 15:30:07 +0000 object(DateTime)#2 (3) { ["date"]=> string(34) "292277026596-12-04 15:30:07.000000 ["timezone_type"]=> int(1) ["timezone"]=> string(6) "+00:00" } Actual result: -------------- string(33) "292277026596-12-04 15:30:07 +0000" bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=75992&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75992&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75992&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75992&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75992&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75992&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75992&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75992&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75992&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75992&r=support Expected behavior: https://bugs.php.net/fix.php?id=75992&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75992&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75992&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75992&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75992&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75992&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75992&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75992&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75992&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75992&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75992&r=mysqlcfg
