# maxdb_num_rows

(PECL maxdb:1.0-7.6.00.38)

maxdb_num_rows — Gets the number of rows in a result

### Description

Procedural style:

int maxdb_num_rows ( resource `$result` )

Object oriented style (property):

maxdb
int$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.

### Return Values

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.

### Examples

Example#1 Object oriented style

`<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = $maxdb->query("SELECT cno, name FROM hotel.customer ORDER BY name")) {
/* determine number of rows result set */
$row_cnt = $result->num_rows;
printf("Result set has %d rows.\n", $row_cnt);
/* close result set */
$result->close();
}
/* close connection */
$maxdb->close();
?>`

Example#2 Procedural style

`<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
if ($result = maxdb_query($link, "SELECT cno, name FROM hotel.customer ORDER BY name")) {
/* determine number of rows result set */
$row_cnt = maxdb_num_rows($result);
printf("Result set has %d rows.\n", $row_cnt);
/* close result set */
maxdb_free_result($result);
}
/* close connection */
maxdb_close($link);
?>`

The above examples would produce the following output:

    Result set has 15 rows.
