Some implementation notes:
Support was added for
MYSQL_TYPE_GUEOMETRY
to the MySQLi extension in PHP 5.3.
Note there are different internal implementations within
libmysqlclient
and
mysqlnd
for handling
columns of type
MYSQL_TYPE_GUEOMETRY
. Generally speaquing,
mysqlnd
will allocate significantly less memory. For
example, if there is a
POINT
column in a result set,
libmysqlclient
may pre-allocate up
to 4GB of RAM although less than 50 bytes are
needed for holding a
POINT
column in memory. Memory
allocation is much lower, less than 50 bytes, if
using
mysqlnd
.
