<?php
class Film {
    protected $queryCriteria;

    public function where($key, $value)
    {
        $this->queryCriteria .= "Findind the Film by $key:$value\n";
        return $this; 
    }

    public function all()
    {
        echo $this->queryCriteria;
    }
}

class FilmRepository {
    protected $film;

    public function __construct(Film $film)
    {
        $this->film = $film;
    }

    public function criteria(array $criteria)
    {
        //logic for finding by criteria here
        $this->film = $this->film->where('title', 'The Lord Of The Rings')->where('length', '120');
        return $this;
    }

    public function all()
    {
        echo $this->film->all();
    }
}


//Then you can use:
$films = new FilmRepository(new Film());
$films->criteria([])->all();
