When ob_gzhandler or zlib.output_compression is switched on, ob_get_length() should report the compressed length, however it reports the uncompressed length.

I found an old bug - #12631 - that is identical to this, but it seems it was fixed a while ago, and then "unfixed".

I cannot seem to work around it with strlen(ob_get_contents()).

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

For performance reasons compression of the buffer (ob_gzhandler) is only done at the termination of the script once all the output has been collected.
