<?php
$animals = array(

    array(1, 'dog', 'Peaches', 12.3),
    array(2, 'horse', 'Smarty', 350.0),
);

$insert = 'INSERT INTO animals (id, breed, name, weight)
    VALUES (?, ?, ?, ?)';
$stmt = db2_prepare($conn, $insert);
if ($stmt) {
    foreach ($animals as $animal) {
        $result = db2_execute($stmt, $animal);
    }
}

<?php

$conn = db2_connect("SAMPLE", "db2admin", "password123");

$query = 'SELECT * FROM XMLTABLE(
    XMLNAMESPACES (DEFAULT \'http://posample.org\'),
    \'db2-fn:xmlcolumn("CUSTOMER.INFO")/customerinfo\'
    COLUMNS
    "CID" VARCHAR (50) PATH \'@Cid\',

$stmt = db2_prepare($conn, $query);

$name = 'Kathy Smith';

if ($stmt) {
    db2_bind_param($stmt, 1, "name", DB2_PARAM_IN);
    db2_execute($stmt);

    while($row = db2_fetch_object($stmt)){
    printf("$row->CID     $row->NAME     $row->PHONE\n");
