int maxdb_num_rows ( resource $result )

Procedural style

Object oriented style

int $maxdb->num_rows;

Returns the number of rows in the result set.

The use of maxdb_num_rows() depends on whether you use buffered or unbuffered result sets. In case you use unbuffered resultsets maxdb_num_rows() will not correct the correct number of rows until all the rows in the result have been retrieved.

Returns:

Returns number of rows in the result set.

Note:

If the number of rows is greater than maximal int value, the number will be returned as a string.
