msql_free_result — Free result memory
msql_free_result() frees the memory associated with query_identifier. When PHP completes a request, this memory is freed automatically, so you only need to call this function when you want to make sure you don't use too much memory while the script is running.
成功时返回 TRUE， 或者在失败时返回 FALSE.
