Screen freezing

[marabesi]

Hello guys,

I've been using Ubuntu for a while and I tried to run the code shown in README.md file but my screen just freeze when I run it.

<?php
require 'vendor/autoload.php';

use Gui\Application;
use Gui\Components\Button;

$application = new Application();

$application->on('start', function() use ($application) {
    $button = (new Button())
        ->setLeft(40)
        ->setTop(100)
        ->setWidth(200)
        ->setValue('Look, I\'m a button!');

    $button->on('click', function() use ($button) {
        $button->setValue('Look, I\'m a clicked button!');
    });
});

$application->run();

My O.S : Ubuntu 14.04

@ricardofontanelli I can't access my terminal after execute the php script. I have to reboot to get my machine working again , thought, I haven't tried php 7. This error can occur because my php version is old
