mysqlnd.fetch_data_copy long
Enforce copying result sets from the internal result set buffers into
PHP variables instead of using the default reference and copy-on-write
logic. Please, see the memory management implementation notes for
further details.
Copying result sets instead of having PHP variables reference them
allows releasing the memory occupied for the PHP variables earlier.
Depending on the user API code, the actual database quries and the
size of their result sets this may reduce the memory footprint of
mysqlnd.
Do not set if using PDO_MySQL. PDO_MySQL has not yet been updated to
support the new fetch mode.
Appreciate your time.
