#36383 [Opn]: ob_implicit_flush() does not disable output buffering

ID: 36383 Updated by: mike@php.net Reported By: david at acz dot org Status: Open -Bug Type: Output Control +Bug Type: Documentation problem Operating System: Linux PHP Version: 5.1-200602151530 New Comment: This is a documentation problem. Unlike the manual says, ob_implicit_flush() does neither end output buffering, nor does it flush the current output buffer. It just causes a flush() when something actually gets written to the webserver.

This is not the case. If this is indeed the correct behavior, please update the documentation to reflect that and add an example such as the following: ob_implicit_flush(true); while (@ob_end_flush()); Reproduce code: --------------- ob_start(); ob_implicit_flush(true); var_dump(ob_end_flush()); Expected result: ---------------- bool(false) Actual result: -------------- bool(true) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=36383&edit=1
