Bug #74399 [Opn->Ver]: ob_*clean* methods do not respect missing cleanable flag; same for flushing

Edit report at https://bugs.php.net/bug.php?id=74399&edit=1 ID: 74399 Updated by: requinix@php.net Reported by: krody dot robi at gmail dot com -Summary: ob_*clean* methods do not respect missing cleanable flag +Summary: ob_*clean* methods do not respect missing cleanable flag; same for flushing -Status: Open +Status: Verified Type: Bug Package: Output Control Operating System: Irrelevant -PHP Version: Irrelevant +PHP Version: 7.1.3 Block user comment: N Private report: N New Comment: Goes back to when the flags were introduced in 5.4: https://3v4l.org/G1Eqn Indeed, CLEANABLE only affects ob_clean() and FLUSHABLE only affects ob_flush(). Looks like it would be fairly straightforward to add in. The alternative would be adjusting the docs, but having those functions respect the flags makes sense to me. And in the case of ob_end_clean and ob_end_flush I would expect both the cleanable/flushable and the removable flags to be required.
