There is this plugin(WhichBrowser->www.whichbrowser.net) i want to use in my project. Sorry i can't use composer because my host doesn't allow it. This is how it goes by:
Code:
<?php
// libraries/parse.php

//uncomment this and it prints(No direct script access allowed!)

/*
if(!defined(BASEPATH))
exit('No direct script access allowed!');
*/
use WhichBrowser\Parser;

require_once APPPATH.'third_party/Parser-2.0.16/bootstrap.php';

//class Parse{

class Parse extends Parser{

/**/
//public function __construct(){
//self::Parser($_SERVER['HTTP_USER_AGENT']);

//require_once APPPATH.'third_party/Parser-2.0.16/bootstrap.php';


//    }
/**/

}

in my controller's index method:
Code:
$this->load->library('parse', $_SERVER['HTTP_USER_AGENT']);
echo 'You are using: '.$this->parse->toString(); // prints 'You are usng an unknown browser' instead of 'You are using Opera Mini 8.0 on Nokia C3-00 running Series40'
anyway to fix this??

I would create in a CodeIgniter style a library Which_browser. In its constructor I would put
Code:
require_once APPPATH.'third_party/Parser-2.0.16/bootstrap.php';

Then I would see what methods this new library would need and I would instantiate the external class wherever it is necessary for implementation of these methods.

For most simple usage the buildin user agent library is excelent. Have you tried using this or do you need a better detection rate in bot names for example?

I think, it depends on the API that is provided. For simple packages this approach is good.

For something more complex a unique approach would be needed maybe, I have not faced such case yet.

Here is a simpler approach for this package: https://github.com/felixgirault/multiplayer

Code:
<?php defined('BASEPATH') OR exit('No direct script access allowed.');

/**
* @author Ivan Tcholakov <[email protected]>, 2014
* @license The MIT License, http://opensource.org/licenses/MIT
*/

class Multiplayer extends \Multiplayer\Multiplayer {

    public function __construct($config = array()) {

        if (!is_array($config)) {
            $config = array();
        }

        parent::__construct($config);
    }

}

It depends on how the package fits to CodeIgniter libraries way.
