What happens if both mod_gzip and PHP's ob_gzhandler are enabled?

If both mod_gzip (configured to compress .php) and PHP's own compression routine (ob_gzhandler enabled on the .php page) are enabled at the same time, what happens?

Does one take precedence over another?
Is the PHP page double-compressed?
(The pages load fine, not garbled or anything)
