(PECL maxdb >= 1.0)
maxdb_num_rows -- maxdb::num_rows — Gets the number of rows in a result
Procedural style
$result
   )Object oriented style
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 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.
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 example will output something similar to:
Result set has 15 rows.
