From: php at login dot hedim dot ch Operating system: PHP version: 5.6.17 Package: Output Control Bug Type: Bug Bug description:Output handler flags for ob_end_clean and ob_end_flush Description: ------------ According to http://php.net/manual/en/function.ob-end-clean.php: The output buffer must be started by ob_start() with PHP_OUTPUT_HANDLER_CLEANABLE and PHP_OUTPUT_HANDLER_REMOVABLE flags. Otherwise ob_end_clean() will not work. However, ob_end_clean() seems to work with only PHP_OUTPUT_HANDLER_REMOVABLE. According to http://php.net/manual/en/function.ob-end-flush.php: The output buffer must be started by ob_start() with PHP_OUTPUT_HANDLER_FLUSHABLE and PHP_OUTPUT_HANDLER_REMOVABLE flags. Otherwise ob_end_flush() will not work. However, ob_end_flush() seems to work with only PHP_OUTPUT_HANDLER_REMOVABLE. The test script below shows the problem with ob_end_clean(). To see the problem with ob_end_flush(), simply replace ob_end_clean() with ob_end_flush(). Test script: --------------- ob_start(null, 0, PHP_OUTPUT_HANDLER_REMOVABLE); echo "1"; ob_end_clean(); echo "2"; Expected result: ---------------- A notice from ob_end_clean() and output "12" Actual result: -------------- Output "2" -- Edit bug report at https://bugs.php.net/bug.php?id=71486&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71486&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71486&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71486&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71486&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71486&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71486&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71486&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71486&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71486&r=support Expected behavior: https://bugs.php.net/fix.php?id=71486&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71486&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71486&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71486&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71486&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71486&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71486&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71486&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71486&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71486&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71486&r=mysqlcfg
