I am wondering why the call to ob_get_clean and ob_get_contents does not
trigger the callback function registered with ob_start('mycallback')

I don't want to dump buffer to the browser but instead need to just store
results in a variable, thus using `ob_get_clean()`
but why it's my callback being executed during this call?
It's actually in the documentation and ob_get_clean is not listed among the
functions that trigger the callback.

Is there a good reason why callback not fired for these functions?

You could at least have told what PHP version you're using...
The output control layer implementation has been replaced in 5.4.

Despite this list being neither a bug tracker nor a support forum:
- Reproduce script?
- Expected result?
- Actual result?
- In which version did it work "correctly" last?

Thank you.
