You could also change `Rest` to be a singleton and call an instance of it, but beware of this antipattern. | You don't call send\_response() in an object context, as the error message says.
Either you create an instance and call everything on that instance (IMHO the right way), or you do everything statically, including the constructor (you may want to have a intialization method instead) and the properties. |
7,779,994 | I am having trouble calling a specific method from another class in my app. I have a class, Rest, that determines various settings, etc. about a particular request received by the server and creates a Rest object with the properties of the request.

] | You can create a `Rest` instance in `User`:
```
public static function index() {
// Do stuff
$rest = new Rest;
$rest::send_response($response_data);
}
```
You could also change `Rest` to be a singleton and call an instance of it, but beware of this antipattern. | You need to create an instance first.

class Users {
public static function index() {
// Do stuff
$rest = new Rest();
$rest->send_response($response_data);

I know this is a lot of code, but I wrote it showing you how to correctly manage dynamic allocated memory and how to correctly use functions like `strtok` and `realloc`, because you see a lot of wrong usage of these functions.
Of course you can make it better with more performanc... |
