PHP eZContentObjectVersion::cloneVersion方法代码示例

    /**

     * If version number is given as argument that version is used to create a copy.
     *
     * Transaction unsafe. If you call several transaction unsafe methods you must enclose
     * the calls within a db transaction; thus within db->begin and db->commit.
