Bug #64977 [Asn]: ob_start() fails when passed default parameters

Edit report at https://bugs.php.net/bug.php?id=64977&edit=1 ID: 64977 Updated by: mike@php.net Reported by: rewilliams at newtekemail dot com Summary: ob_start() fails when passed default parameters Status: Assigned Type: Bug Package: Documentation problem PHP Version: 5.5.0RC2 Assigned To: aharvey Block user comment: N Private report: N New Comment: See also Doc Bug #62019 Previous Comments: ------------------------------------------------------------------------ [2014-11-19 09:31:48] mike@php.net PHP_OUTPUT_HANDLER_STARTED just indicates that the handler has been called previously with PHP_OUTPUT_HANDLER_START set, so it would not get that flag again, unless it has also seen PHP_OUTPUT_HANDLER_FINAL in the meantime. So: handler(PHP_OUTPUT_HANDLER_START) => flags |= STARTED handler(PHP_OUTPUT_HANDLER_FINAL) => flags ^= STARTED PHP_OUTPUT_HANDLER_DISABLED: Internal output handlers can mark them self as disabled with php_output_handler_hook(PHP_OUTPUT_HANDLER_HOOK_DISABLE), when they f.e. detect an error; see README.NEW-OUTPUT-API. Also, when a call to an internal or userland handler fails, or the userland handler returns FALSE. ------------------------------------------------------------------------ [2013-10-01 18:37:07] aharvey@php.net OK, documentation is done except for the PHP_OUTPUT_BUFFER_STARTED and PHP_OUTPUT_BUFFER_DISABLED constants, mostly because I can't figure out how they're useful. Mike, help please? :) ------------------------------------------------------------------------ [2013-10-01 18:35:20] aharvey@php.net Automatic comment from SVN on behalf of aharvey Revision: http://svn.php.net/viewvc/?view=revision&revision=331632 Log: Document the ob_start() changes in PHP 5.4. Mostly fixes doc bug #64977 (ob_start() fails when passed default parameters). ------------------------------------------------------------------------ [2013-09-27 18:44:22] aharvey@php.net We probably should have picked that up at the time. Whoops. OK, I'll assign this to myself and figure out how to document it. Probably won't be today. ------------------------------------------------------------------------ [2013-09-27 08:05:06] mike@php.net Duh, unfortunately pretty much the opposite: bool(true) -> int(1) & ~0xf == 0 The first bits are reserved for the OB handler type (internal/user) and thus ignored, so flags end up as zero, which in turn means the handler is neither removeable, nor flushable, nor cleanable. I suspect, I could have done better. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
