Support was added for <em>MYSQL_TYPE_GEOMETRY</em>
to the MySQLi extension in PHP 5.3.

<p class="para">
Note there are different internal implementations within
<em>libmysqlclient</em> and <em>mysqlnd</em> for handling
columns of type <em>MYSQL_TYPE_GEOMETRY</em>. Generally speaking,
<em>mysqlnd</em> will allocate significantly less memory. For
example, if there is a <em>POINT</em>
column in a result set, <em>libmysqlclient</em> may pre-allocate up
to 4GB of RAM although less than 50 bytes are
needed for holding a <em>POINT</em> column in memory. Memory
allocation is much lower, less than 50 bytes, if
using <em>mysqlnd</em>.
