Edit report at https://bugs.php.net/bug.php?id=66758&edit=1 ID: 66758 Updated by: mike@php.net Reported by: krzysiekpiasecki at yahoo dot com Summary: Flags and control output buffering functions -Status: Not a bug +Status: Re-Opened -Type: Bug +Type: Documentation Problem Package: Output Control Operating System: MAC OS X 10.8.5 PHP Version: 5.5.8 Assigned To: mike Block user comment: N Private report: N New Comment: Silly me. Re-opening as a doc issue. JFYI the behavior is that way since PHP-5.4.0 Previous Comments: ------------------------------------------------------------------------ [2014-07-07 07:47:58] mike@php.net Control is more fine grained now; you need to add PHP_OUTPUT_HANDLER_REMOVABLE to be able to pop it off the stack: ob_start(null, 0, PHP_OUTPUT_HANDLER_CLEANABLE | PHP_OUTPUT_HANDLER_REMOVABLE); Or if flushing is also allowed (good idea), you can use PHP_OUTPUT_HANDLER_STDFLAGS, which includes all three capabilities. ------------------------------------------------------------------------ [2014-07-07 05:26:43] yohgaki@php.net 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'. ------------------------------------------------------------------------ [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
