Summary: ob_start callback get passed empty string
Status: Not a bug
Type: Bug
Package: Output Control
Operating System: Arch 32 bit
PHP Version: 5.4.0
Block user comment: N
Private report: N
New Comment:
Unless ob_start callback specification has changed that for
ob_clean/ob_end_clean, the output is discarded before calling the callback,
then this is a bug. And I have scan the PHP 5.4 changelog and couldn't find
anything mentioning this change.
So let me help by showing where the problem is
In line 1226 of output.c in the distributed PHP 5.4.0 source,
if (flags & PHP_OUTPUT_POP_DISCARD) {
context.op |= PHP_OUTPUT_HANDLER_CLEAN;
orphan->buffer.used = 0;
}
php_output_handler_op(orphan, &context);
orphan->buffer.used should not be set to 0 before calling the callback,
otherwise the callback will be called with empty buffer.
And likewise in line 300 in php_output_clean
So, no, it isn't about appending $output to $buffer.

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
You should append $output to $buffer.
