Frees all resources for the specified statement. The statement cannot be used
after <function>sqlsrv_free_stmt</function> has been called on it. If
<function>sqlsrv_free_stmt</function> is called on an in-progress statement
that alters server state, statement execution is terminated and the statement
is rolled back.

The main difference between <function>sqlsrv_free_stmt</function> and
<function>sqlsrv_cancel</function> is that a statement resource cancelled with
<function>sqlsrv_cancel</function> can be re-executed if it was created with
<function>sqlsrv_prepare</function>. A statement resource cancelled with
<function>sqlsrv_free_statement</function> cannot be re-executed.
