From: charlesw at ex-situ dot com Operating system: CentOS / OSX / Other PHP version: 5.6.8 Package: SPL related Bug Type: Bug Bug description:SPL objects (DateInterval) and isset Description: ------------ Testing public properties on DateInterval objects with isset returns false even when they contain data. Running a print_r or var_dump on the object BEFORE testing isset will provide the desired result. Test script: --------------- $currentDate = new DateTime(); $targetDate = new DateTime('2015-03-05 11:11:11'); $interval = $currentDate->diff($targetDate); // var_dump($interval); // Uncomment and isset will give the expected response var_dump($interval->y); var_dump($interval->m); var_dump(isset($interval->y)); var_dump(isset($interval->m)); Expected result: ---------------- int(0) int(2) bool(true) bool(true) Actual result: -------------- int(0) int(2) bool(false) bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=69587&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69587&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69587&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69587&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69587&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69587&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69587&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69587&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69587&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69587&r=support Expected behavior: https://bugs.php.net/fix.php?id=69587&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69587&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69587&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69587&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69587&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69587&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69587&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69587&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69587&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69587&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69587&r=mysqlcfg
