How to use $this in closure in php

Question

I have function like this:

class Service {
    function delete_user($username) {   
        ...
        $sessions = $this->config->sessions;
        $t         


        

Answer 1

You can just cast it to something else:

$a = $this;
$this->config->sessions = array_filter($sessions, function($session) use ($a, $username){
   return $a->get_username($session->token) != $username;
});

You'll also need to pass $username through otherwise it'll always be true.
