Description

Procedural style:

int maxdb_num_fields ( resource result )

Object oriented style (property):

class result {

int field_count

}

maxdb_num_fields() returns the number of fields from specified result set.

Example

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 * FROM hotel.city ORDER BY zip")) {

   /* determine number of fields in result set */
   $field_cnt = $result->field_count;

   printf("Result set has %d fields.\n", $field_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 * FROM hotel.city ORDER BY zip")) {

   /* determine number of fields in result set */
   $field_cnt = maxdb_num_fields($result);

   printf("Result set has %d fields.\n", $field_cnt);

   /* close result set */
   maxdb_free_result($result);
}

/* close connection */
maxdb_close($link);
?>

The above examples would produce the following output:

Result set has 3 fields.
