Req #71364 [NEW]: restore_error_handler() should return the actual callable

From: hujuice at inservibile dot org Operating system: Linux PHP version: 5.6Git-2016-01-14 (snap) Package: Unknown/Other Function Bug Type: Feature/Change Request Bug description:restore_error_handler() should return the actual callable Description: ------------ restore_error_handler() returns always true, no info. But in complex situations where included files could add other handlers, there's no way to be sure that the restored handler is the wanted one. This doubt could be prevented if restore_error_handler() would return the actual callable or null if at the end of the stack. Test script: --------------- file1.php ========= <?php set_error_handler('someFunct'); include 'file2.php'; restore_error_handler(); // Not enough! file2.php ========= <?php set_error_handler('anotherFunct'); Expected result: ---------------- NOT CORRECT! It could be an useful feature file1.php ========= <?php $prev = set_error_handler('someFunct'); include 'file2.php'; do { $actual = restore_error_handler(); // Run twice } while ($actual != $prev); file2.php ========= <?php set_error_handler('anotherFunct'); -- Edit bug report at https://bugs.php.net/bug.php?id=71364&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71364&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71364&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71364&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71364&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71364&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71364&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71364&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71364&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71364&r=support Expected behavior: https://bugs.php.net/fix.php?id=71364&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71364&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71364&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71364&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71364&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71364&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71364&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71364&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71364&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71364&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71364&r=mysqlcfg
