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

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'])){

You can not access class function directly like this.You need to create class object first and then call the function with object variable.
It's better to save class code in a separate file and include it in the above give file at the top to avoid errors.
E.g:
// $config as array, You need it to set in construct method.check construct method.
$config = [
"id" => ENTER_ID,
"key" => ENTER_KEY,
"decode" => true, //Optional you can leave this ,default is true anyway.
];
$ServerPilot_Obj = New ServerPilot($config);
$ServerPilot_Obj->app_create( $name, $sysuserid, $runtime, $domains = array());
