(PECL CUBRID >= 8.3.0)
Get the number of rows in the result set
int cubrid_num_rows ( resource $result )
The cubrid_num_rows() function is used to get the number of rows from the query result. You can use it only when the query executed is a select statement. When you want to know such value for INSERT, UPDATE, or DELETE query, you have to use the cubrid_affected_rows() function.
Note: The cubrid_num_rows() function can only be used for synchronous query; it returns 0 when it is used for asynchronous query.
Parameters:
result
result
comes from a call to cubrid_execute(), cubrid_query() and cubrid_prepare()
Returns:
Number of rows, when process is successful.
0 when the query was done in async mode.
-1, if SQL statement is not SELECT.
FALSE
when process is unsuccessful.
Examples:

<?php $conn = cubrid_connect("localhost", 33000, "demodb", "dba"); $req = cubrid_execute($conn, "SELECT * FROM code"); $row_num = cubrid_num_rows($req); $col_num = cubrid_num_cols($req); printf("Row Num: %d\nColumn Num: %d\n", $row_num, $col_num); cubrid_disconnect($conn); ?>
