Doc->Bug #66758 [Opn]: Flags and control output buffering functions

Edit report at https://bugs.php.net/bug.php?id=66758&edit=1 ID: 66758 Updated by: yohgaki@php.net Reported by: krzysiekpiasecki at yahoo dot com Summary: Flags and control output buffering functions Status: Open -Type: Documentation Problem +Type: Bug Package: Output Control Operating System: MAC OS X 10.8.5 PHP Version: 5.5.8 -Assigned To: +Assigned To: mike Block user comment: N Private report: N New Comment: Verified on my Fedora 20 with PHP 5.5.14. This seems a bug rather than doc issue. What do you think, mike? ob_start(null, 0, PHP_OUTPUT_HANDLER_CLEANABLE); echo 'AAA'; ob_end_clean(); This code does not clean buffer, raises error, then outputs 'AAA'. Previous Comments: ------------------------------------------------------------------------ [2014-02-23 22:46:36] krzysiekpiasecki at yahoo dot com Version is 5.5.8 ------------------------------------------------------------------------ [2014-02-23 22:43:42] krzysiekpiasecki at yahoo dot com Description: ------------ From PHP manual: PHP_OUTPUT_HANDLER_CLEANABLE const control access to functions: ob_clean(), ob_end_clean(), and ob_get_clean(). Using ob_end_clean(), there is a notice: "ob_end_clean(): failed to discard buffer of default output handler (1)". Using ob_get_clean(), there is even a double notice: "ob_get_clean(): failed to delete buffer of default output handler (1)". I understand, that only cleanable buffer can't be flush and delete. So why in manual these functions are under control PHP_OUTPUT_HANDLER_CLEANABLE const? I'm confused. Test script: --------------- ob_start(null, 0, PHP_OUTPUT_HANDLER_CLEANABLE); ob_end_clean(); ob_start(null, 0, PHP_OUTPUT_HANDLER_CLEANABLE); ob_get_clean(); Expected result: ---------------- No notice, and no buffer after function invocation. Actual result: -------------- ob_end_clean() produces notice: Notice: ob_end_clean(): failed to discard buffer of default output handler (1) ob_get_clean() produces double notice: Notice: ob_get_clean(): failed to discard buffer of default output handler (2) Notice: ob_get_clean(): failed to discard buffer of default output handler (2) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66758&edit=1
