cubrid_num_rows — Get the number of rows in the result set

### Description

cubrid_num_rows(resource `$result`): int

The cubrid_num_rows() function is used to get the number of rows from the query result. It can be used for `SELECT` statements. For `INSERT`, `UPDATE`, or `DELETE` queries, 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()

### Return Values

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

Example #1 cubrid_num_rows() example

`<?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);
?>`

The above example will output:

    Row Num: 6
    Column Num: 2
