How do I use an external library?

Hi guys, I have this external library called "simplehtmldom.php" but I don't know how to use it in my phalcon project.

I have this code:

<?php
    require 'simple_html_dom.php';

    $url = 'https://porrua.mx/busqueda/ebooks/9780545229937';
    $html=file_get_html($url); //Devuelve un array con contenido de la página

    $posts=$html->find('div[class=contenthover]'); 
    foreach ($posts as $post) {
        $link=$post->find('h5',3);     
        $title=$link->innertext;
        echo $title,"\n";
    }

?>

Now I want to do the exact same thing in a Controller. But I don't know how to import and use the 'simplehtmldom.php' library inside Phalcon. I guess I just can't use the 'require' command. Can you please point me on how to use this library?

I'm still a beginner with Phalcon so I'm having trouble understanding all of these. Thank you so much for your help!

You can just use require command, no problem with that.

Yeah - just put that require statement in your bootstrap, then use the methods as you've shown in your example.

If you really wanted to, I suppose you could make a service out of it, then access the methods through the Dependency Injector. That's probably the method most inline with the MVC philosophy - but there is something to be said for just gettin' 'er done
