Bug #72160 [NEW]: isset() produces unexpected result

From: godmod at eqdkp-plus dot eu Operating system: Linux PHP version: 7.0.6 Package: Class/Object related Bug Type: Bug Bug description:isset() produces unexpected result Description: ------------ In PHP < 7.0.6, the result for var_dump($this->user->style['template_path']); var_dump(isset($this->user)); var_dump(isset($this->user->style)); var_dump(isset($this->user->style['template_path'])); is, as expected: string(6) "modern" bool(false) bool(true) bool(true) But since the 7.0.6 release, it is not as expected, it is string(6) "modern" bool(false) bool(false) bool(false) Why does the isset() return false, for the exact same code? Please note that $user is handled by __get() method -- Edit bug report at https://bugs.php.net/bug.php?id=72160&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72160&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72160&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72160&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72160&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72160&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72160&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72160&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72160&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72160&r=support Expected behavior: https://bugs.php.net/fix.php?id=72160&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72160&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72160&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72160&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72160&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72160&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72160&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72160&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72160&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72160&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72160&r=mysqlcfg
