ID: 64977 Updated by: a...@php.net Reported by: rewilliams at newtekemail dot com Summary: ob_start() fails when passed default parameters -Status: Open +Status: Analyzed Type: Bug Package: Scripting Engine problem PHP Version: 5.5.0RC2 Block user comment: N Private report: N New Comment: This is more like a documentation bug. There is a bunch of constants undocumented http://lxr.php.net/xref/PHP_5_4/main/output.c#204 . Also the third ob_start() argument can be not only true/false, you can pass various flags there. As such, if you change your first line ob_start(null, 0, PHP_OUTPUT_HANDLER_REMOVABLE) no warnings will be to see. Please change this bug to be a documentation one. Or you could even fix the docs. Previous Comments: ------------------------------------------------------------------------ [2013-06-05 20:03:11] rewilliams at newtekemail dot com Description: ------------ Calling ob_start() with explicit parameters that match the defaults (using null to get past the first one, as documented), the various functions to end output buffering generate notices, which are also added to the buffered content. For example, ob_get_clean() returns the following: ob_get_clean(): failed to discard buffer of default output handler [...] ob_get_clean(): failed to delete buffer of default output handler (0) in [...] It looks like output is spit out just as though buffering were not enabled, *and* the buffer gets saved - albeit with the buffering-related notices mixed in. Testing at <http://sandbox.onlinephpfunctions.com>, it appears the bug was introduced in 5.4 (it works in 5.3.23) and continues through the latest version of 5.5. Test script: --------------- <?php ob_start(null, 0, true); echo 'hello world'; $foo = ob_get_clean(); var_dump($foo) ?> Expected result: ---------------- string(11) "hello world" Actual result: -------------- PHP Notice: ob_get_clean(): failed to discard buffer of default output handler (0) in [...] on line 5 PHP Notice: ob_get_clean(): failed to delete buffer of default output handler (0) in [...] on line 5 hello world Notice: ob_get_clean(): failed to discard buffer of default output handler (0) in [...] on line 5 Notice: ob_get_clean(): failed to delete buffer of default output handler (0) in [...] on line 5 string(11) "hello world" ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64977&edit=1
