Can't create database from coding but can from cpanel - php

Question

The database test_new_1 is able to create for the user testcom directly from the cpanel, But not able to create through php. Another server it is working properly, the only difference username and database prefix is same in that server.
Error Shows:
Error creating database: Access denied for user 'testcom'#'localhost' to database 'test_new_1'
PHP
// Create connection
$conn = mysqli_connect('localhost', 'testcom', '123456');
// Check connection
if (!$conn)
{
die("Connection failed: " . mysqli_connect_error());
}
// Create database
$sql = "CREATE DATABASE IF NOT EXISTS test_new_1";
if (mysqli_query($conn, $sql))
{
echo "Database created successfully";
}
else
{
echo "Error creating database: " . mysqli_error($conn);
}

cPanel does not allow you to create databases directly from with MySQL function. You need to use the API provided to you by cPanel:
Download xmlapi.php from https://github.com/CpanelInc/xmlapi-php/blob/master/xmlapi.php then use it:
<?php
include("xmlapi.php");
$db_host = 'yourdomain.com';
$cpaneluser = 'your cpanel username';
$cpanelpass = 'your cpanel password';
$databasename = 'testdb';
$databaseuser = 'test'; // Warning: in most of cases this can't be longer than 8 characters
$databasepass = 'dbpass'; // Warning: be sure the password is strong enough, else the CPanel will reject it
$xmlapi = new xmlapi($db_host);
$xmlapi->password_auth("".$cpaneluser."","".$cpanelpass."");
$xmlapi->set_port(2082);
$xmlapi->set_debug(1);//output actions in the error log 1 for true and 0 false
$xmlapi->set_output('array');//set this for browser output
//create database
$createdb = $xmlapi->api1_query($cpaneluser, "Mysql", "adddb", array($databasename));
//create user
$usr = $xmlapi->api1_query($cpaneluser, "Mysql", "adduser", array($databaseuser, $databasepass));
//add user
$addusr = $xmlapi->api1_query($cpaneluser, "Mysql", "adduserdb", array("".$cpaneluser."_".$databasename."", "".$cpaneluser."_".$databaseuser."", 'all'));
?>
