#24346 [Asn->Csd]: ob_start wrongly optimized out when no callback specified

ID: 24346 Updated by: et@php.net Reported By: pitrou at free dot fr -Status: Assigned +Status: Closed Bug Type: Documentation problem Operating System: Linux PHP Version: 4.3.2 Assigned To: davey New Comment: This bug has been fixed in CVS. In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. Callbacks are now documented properly in http://de3.php.net/manual/en/language.pseudo-types.php Previous Comments: ------------------------------------------------------------------------ [2003-06-30 09:26:23] philip@php.net Davey is actually the one working on this :) Assigned->Davey ------------------------------------------------------------------------ [2003-06-30 03:31:02] derick@php.net Point 1 has been documented now, assigning to philip as he's working on point 2. ------------------------------------------------------------------------ [2003-06-27 04:45:01] derick@php.net It's indeed a change, but still, it's right as it is now. I'm changing this to a doc problem: 1. the return value is not documented 2. this function can also be used with the array() syntax to call methods of an object. ------------------------------------------------------------------------ [2003-06-26 10:15:28] pitrou at free dot fr Ok, then there's a compatibility problem (it used to work before). Also the documentation is bogus too: http://www.php.net/manual/en/function.ob-start.php It doesn't mention the return value, the return type is even supposed to be "void". How can I know I'm supposed to check the return value ? In the end I think a bad callback parameter to ob_start is enough to print an error message on screen (just as calling a function which doesn't exist prints an error message on screen). Thanks for the reply. ------------------------------------------------------------------------ [2003-06-26 09:38:18] derick@php.net You should use NO parameter if you don't want a handler. PHP 4.3.2 correctly returns FALSE in this case. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
