Calling a custom function help

Ok so i made a function like so

PHP:

public function TestFunction() {
console("Test");
}

But i dont know how to call the function i trie $this->TestFunction(); but it didn't work. Never done much with creating functions.

The function itself looks fine to me. How are you calling it? With a command?

Yes im calling it with a command.

Hmm, looks fine to me. You're doing everything right from what I can see, I usually use functions to process info and output something. I'm no php pro but my functions usually have some sort of input or return something. @Falk , any suggestions?

Post the whole code?

Nvm i figured out what i did but does anyone know how to get the username of a player that just spawned?

PHP:

public function init(){
            $this->api->addHandler("player.join", array($this,"onJoin"));
}

public function onJoin($p){
            $username = $p->username;
}

Use "player.spawn" for newly spawned.
