<para>
This method constructs a new <classname>mysqli_result</classname> object.
</para>
<para>
It can be used to create the <classname>mysqli_result</classname> object
after calling the <function>mysqli_real_query</function> or
<function>mysqli_multi_query</function> function. Constructing the object
manually is equivalent to calling the <function>mysqli_store_result</function>
or <function>mysqli_use_result</function> function.

<para>
The result mode can be one of 2 constants indicating how the result will
be returned from the MySQL server.
</para>
<para>
<constant>MYSQLI_STORE_RESULT</constant> (default) - creates a
<classname>mysqli_result</classname> object with buffered result set.
</para>
<para>
<constant>MYSQLI_USE_RESULT</constant> - creates a
<classname>mysqli_result</classname> object with unbuffered result set.
As long as there are pending records waiting to be fetched, the
connection line will be busy and all subsequent calls will return error
<literal>Commands out of sync</literal>. To avoid the error all records
must be fetched from the server or the result set must be discarded by
calling <function>mysqli_free_result</function>. The connection must
remain open for the rows to be fetched.
