Mysql_num_rows

If you use mysql_unbuffered_query(), mysql_num_rows() will not return the correct value until all the rows in the result set have been retrieved. The mysqli_ num _ rows () function returns the number of rows in a result set. Returns the number of rows in the result set. The behaviour of mysqli_ num _ rows () depends on whether buffered or unbuffered result sets are being used. For unbuffered result sets, mysqli_ num _ rows () will not return the correct number of rows until all the rows in the result have been retrieved.
