Elephant.io integration php - php

Question

Using only a simple file I can get elephant.io to work, but If I'm trying to integrate it inside an class, it won't work.
The reason why it won't work is that it says I can't use use elephant ... inside a class or function.
How would I integrate elephant.io in an already existing class ?
To be more specific , I'm trying to integrate elephant.io into codeigniter framework.
function tester() {
use ElephantIO\Client,
ElephantIO\Engine\SocketIO\Version1X;
require __DIR__ . '/vendor/autoload.php';
$client = new Client(new Version1X('http://www.textbasedmafiagame.com:8080'));
$client->initialize();
$client->emit('broadcast2', ['foo' => 'utførte et biltyveri']);
$client->close();
}
and get no response or outcome, but i do get:
use not allowed inside a function
and
Parse error: syntax error, unexpected 'use'

Answer 1

As the error states, the use keyword must be declared in the outermost scope of a file (the global scope) or inside namespace declarations.
Try something along these lines
<?php
use ElephantIO\Client, ElephantIO\Engine\SocketIO\Version1X;
require __DIR__ . '/vendor/autoload.php';
class foo{
public function tester() {
$client = new Client(new Version1X('http://www.textbasedmafiagame.com:8080'));
$client->initialize();
$client->emit('broadcast2', ['foo' => 'utførte et biltyveri']);
$ client->close();
}
}
