where to include composer packages

In phalcon 3.0 you can just load files using phalcon loader. You can include them whereever you want. In service definition or just in loader or whatever.

@Jurigag you mean like this

$loader = new Loader();
$loader->registerDirs(
    array(
        '../autoload.php'
    )
)->register();

or what?

If you mean the vendor/autoload.php, then include it in your loader.php file - if you follow conventional phalcon struct. Otherwise, include it where Phalcon\Loader is initialized.

yes i mean vendor/autoload.php @lajosbencz

and i have only app and public folders no file called loader.php

my first day in phalcon :)

No. auatoload.php file is obviously not directory :) https://github.com/phalcon/cphalcon/blob/master/phalcon/loader.zep#L178

@Jurigag im sorry i don't understand

i have app & public folders now i want to load the compseor packages

where exactly ?and how?

Just load composer autoloader with method i wrote above :)

$loader = new Loader();
$loader->registerFiles(
    array(
        'file.php',
    )
)->register();

gives error

Fatal error: Call to undefined method Phalcon\Loader::registerFiles()

Then you are not using phalcon 3.0 :)
