 New Comment:

Could you possibly add tests for the PHP_OUTPUT_HANDLER_* flags? It would make it much easier for me
to figure out what they're meant to do.

Actually none of these is a "flush" as in ob_flush(), where the output buffer stays on the
stack.

Both ob_get_flush() and ob_end_flush() actually finish the output buffer/handler.

Naming of the userland API is ambiguous, but you can see in the output.c sources, that both of these
functions actually call php_output_end() and not php_output_flush().

Reclassifying as "Doc Bug", wrt PHP_OUTPUT_HANDLER_FLUSHABLE only affects ob_flush().

Thanks anyway!

Description:
------------
According to the manual, ob_get_flush() and ob_end_flush() should fail if
PHP_OUTPUT_HANDLER_FLUSHABLE was not given during ob_start(). That seems like a sensible policy, but
the flag is only checked during ob_flush().

I noticed this bug while reading output.c, I don't actually use those functions.

Test script:
---------------
<?php
ob_start(null, 0, PHP_OUTPUT_HANDLER_REMOVABLE);
print "x\n";
var_dump(ob_get_flush());


Expected result:
----------------
PHP Notice:  ob_get_flush(): failed to flush buffer of default output handler (0) in
ob_get_flush.php on line 4
bool(false)
x

Actual result:
--------------
x
string(2) "x
"
