Dependencies

This package relies on the following libraries to work:

• Guzzle
• Illuminate Support

All above dependencies will be automatically downloaded if you are using Composer to install this package.

Installation

To install this library using Composer, simply run the following command inside your project directory:

composer require risan/sl

Or you may also add risan\sl package into your composer.json file like so:

"require": {
  "risan/sl": "~1.1"
}

And don't forget to run the following composer command to install this library:

composer install

Basic Usage

Here is some basic example to use this library:

<?php
// Include autoloder file.
require 'vendor/autoload.php';

// Create a new instance Sl\Sl.
$sl = new Sl\Sl();

// Search for station.
// Will return Sl\Collections\StationColection.
$stations = $sl->searchStation('Central Station');

// Find for departures.
// Will return Sl\Collections\DepartureColection.
$departures = $sl->departuresFrom($stations->first());

Search for Station

To search for a station, you may use the searchStation() method:

$sl->searchStation(string $query);

For example, if you'd like to find all stations that match the central word, then your code will look like this:

$sl = new Sl\Sl();

$stations = $sl->searchStation('central');

print_r($stations->toArray());

The searchStation() method will automatically perform a HTTP request to sl.se to search for stations that match the given $query. This method will return an instance of Sl\Collections\StationCollection class, which contains a collection of Sl\Station instances.

The StationCollection class itself is a subclass of Illuminate\Support\Collection, so you may leverage the powerful feature of Laravel's collection.

Find Departures

You may also find departures from a specific station using departuresFrom() method:

$sl->departuresFrom(Sl\Station $station);

This method will perform a HTTP request to sl.se website in order to find a list of departures for a given $station. Note that this method requires an argument that must be instance of Sl\Station class.

For example, if you need to find all departures from Slussen station, you can do the following:

$sl = new Sl\Sl();

$slussen = $sl->searchStation('slussen')->first();

$departures = $sl->departuresFrom($slussen);

print_r($departures->toArray());

The $departures will be an instance of Sl\Collections\DepartureCollection which hold a collection of Sl\Departure instances. The DepartureCollection is also a subclass of Illuminate\Support\Collection.

Bus Departures

To filter only the bus departures, call busses method:

$sl->departuresFrom(Sl\Station $station)->busses();

Train Departures

To filter only the train (pendeltåg) departures, call trains() method:

$sl->departuresFrom(Sl\Station $station)->trains();

Metro Departures

To filter only the metro (tunnelbana) departures, call metros() method:

$sl->departuresFrom(Sl\Station $station)->metros();

Tram Departures

To filter only the tram (spårvagn) departures, call trams() method:

$sl->departuresFrom(Sl\Station $station)->metros();

Light Rail Departures

To filter only the light rail (lokalbana) departures, call lightRails() method:

$sl->departuresFrom(Sl\Station $station)->lightRails();

Ship Departures

To filter only the ship or boat departures, call ships() method:

$sl->departuresFrom(Sl\Station $station)->ships();
