* @param attr int <p>
* The attribute that you want to set. It can have one of the following values:
* <table>
* Attribute values
* <tr valign="top">
* <td>Character</td>
* <td>Description</td>
* </tr>
* <tr valign="top">
* <td>MYSQLI_STMT_ATTR_UPDATE_MAX_LENGTH</td>
* <td>
* If set to 1, causes mysqli_stmt_store_result to
* update the metadata MYSQL_FIELD->max_length value.
* </td>
* </tr>
* <tr valign="top">
* <td>MYSQLI_STMT_ATTR_CURSOR_TYPE</td>
* <td>
* Type of cursor to open for statement when mysqli_stmt_execute
* is invoked. mode can be MYSQLI_CURSOR_TYPE_NO_CURSOR
* (the default) or MYSQLI_CURSOR_TYPE_READ_ONLY.
* </td>
* </tr>
* <tr valign="top">
* <td>MYSQLI_STMT_ATTR_PREFETCH_ROWS</td>
* <td>
* Number of rows to fetch from server at a time when using a cursor.
* mode can be in the range from 1 to the maximum
* value of unsigned long. The default is 1.
* </td>
* </tr>
* </table>
* </p>
* <p>
* If you use the MYSQLI_STMT_ATTR_CURSOR_TYPE option with
* MYSQLI_CURSOR_TYPE_READ_ONLY, a cursor is opened for the
* statement when you invoke mysqli_stmt_execute. If there
* is already an open cursor from a previous mysqli_stmt_execute call,
* it closes the cursor before opening a new one. mysqli_stmt_reset
* also closes any open cursor before preparing the statement for re-execution.
* mysqli_stmt_free_result closes any open cursor.
* </p>
* <p>
* If you open a cursor for a prepared statement, mysqli_stmt_store_result
* is unnecessary.
* </p>
* @param mode int <p>The value to assign to the attribute.</p>
* @return bool
