db2_num_fields Returns the number of fields contained in a result set

Description

int db2_num_fields ( resource $stmt )

Returns the number of fields contained in a result set. This is most useful for handling the result sets returned by dynamically generated queries, or for result sets returned by stored procedures, where your application cannot otherwise know how to retrieve and use the results.

Parameters

stmt

A valid statement resource containing a result set.

Return Values

Returns an integer value representing the number of fields in the result set associated with the specified statement resource. Returns FALSE if the statement resource is not a valid input value.

Examples

Example #1 Retrieving the number of fields in a result set

The following example demonstrates how to retrieve the number of fields returned in a result set.

<?php

$sql 
"SELECT id, name, breed, weight FROM animals ORDER BY breed";
$stmt db2_prepare($conn$sql);
db2_execute($stmt$sql);
$columns db2_num_fields($stmt);

echo 
"There are {$columns} columns in the result set.";
?>

The above example will output:

 There are 4 columns in the result set.
