I am trying to use serverPilot API from my website. I have created simple functions like below for sample usage but its giving me error like below

Fatal error: Uncaught Error: Call to undefined function app_create()

I am new in PHP and don't know proper method to declare and use functions. Let me know what I am missing in this? My full PHP code is like below

<?php

if($_SERVER['REQUEST_METHOD'] == "POST" and isset($_POST['createApp'])){

    $name = "sampleName";
    $name = "hello";
    $runtime ="php5.5";
    $password = "Test@123";
    $domains = array("www.example.com","example2.com");
    app_create( $name, $sysuserid, $runtime, $domains = array());

}
else if($_SERVER['REQUEST_METHOD'] == "POST" and isset($_POST['createDb'])){

    $id = 1;
    $name = "hello";
    $username ="testuser";
    $password = "Test@123";

    database_create( $id, $name, $username, $password );

}
else if($_SERVER['REQUEST_METHOD'] == "POST" and isset($_POST['createUser'])){

    $id = 1;
    $name = "hello";
    $password = "Test@123";

    sysuser_create( $id, $name, $password = NULL )();
}
