### What does it gives you?

This package has all sorts of information about countries:

| info            | items |
------------------|-------:|
| taxes           | 32    |
| geometry maps   | 248   |

### Geology and topology maps

Amongst many other information you'll be able to plot country maps:

## Requirements

- PHP 7.0+

## Installing

Use Composer to install it:

```
composer require pragmarx/countries
```

## Instantiating

```php
use PragmaRX\Countries\Package\Countries;

$countries = new Countries();

echo $countries->where('cca2', 'IT')->first()->hydrateCurrencies()->currencies->EUR->coins->frequent->first();

// or calling it statically

echo Countries::where('cca2', 'IT')->first()->hydrateCurrencies()->currencies->EUR->coins->frequent->first();
```

Should both return

```
€1
```

Overloading the default configuration:

```php
use PragmaRX\Countries\Package\Services\Config;

$countries = new Countries(new Config([
    'hydrate' => [
        'elements' => [
            'currencies' => true,
            'flag' => true,
            'timezones' => true,
        ],
    ],
]));
```

#

## Usage

This package is not tied to Laravel and doesn't require it to be installed (we have a [bridge](https://github.com/antonioribeiro/countries-laravel) for this purpose), but it has [Laravel Collections](https://laravel.com/docs/5.6/collections) in its core, all methods in Collections are available, this way you can do things like filter, map, reduce, search, sort, reject, and a lot more. It, actually, uses [Coollection](https://github.com/antonioribeiro/coollection), which is Laravel Collections with a fluent syntax, allowing us to have access to array keys (and values) as object properties.

To get all countries in the data base you just have to:

```php
use PragmaRX\Countries\Package\Countries;

$countries = new Countries();

$all = $countries->all();
```

To get a json you:

```php
return $countries->toJson();
```

Filter by keys and values:

```php
$countries->where('name.common', 'Brazil');
```

Will find Brazil by its common name, which is a

```
#items: array:22 [▼
  "name" => array:3 [▼
    "common" => "Brazil"
    "official" => "Federative Republic of Brazil"
    "native" => array:1 [▼
      "por" => array:2 [▼
        "official" => "República Federativa do Brasil"
        "common" => "Brasil"
      ]
    ]
  ]
```

Or alternatively you can filter like this

```php
$countries->whereNameCommon('Brazil');
```

And, you can go deepeer

```php
$countries->where('name.native.por.common', 'Brasil');
```

Or search by the country top level domain

```php
$countries->where('tld.0', '.ch');
```

To get

```
"name" => array:3 [▼
  "common" => "Switzerland"
  "official" => "Swiss Confederation"
  "native" => array:4 [▶]
]
"tld" => array:1 [▼
  0 => ".ch"
]
```
And use things like pluck

```php
$countries->where('cca3', 'USA')->first()->hydrateStates()->states->pluck('name', 'postal')->toArray();
```

To get

```php
"MA" => "Massachusetts"
"MN" => "Minnesota"
"MT" => "Montana"
"ND" => "North Dakota"
...
```

The package uses a modified Collection which allows you to access properties and methods as objects:

```php
$countries->where('cca3', 'FRA')
         ->first()
         ->borders
         ->first()
         ->name
         ->official;
```

Should give

```
Principality of Andorra
```

Borders hydration is disabled by default, but you can have your borders hydrated easily by calling the hydrate method:

```php
$countries->where('name.common', 'United Kingdom')
         ->hydrate('borders')
         ->first()
         ->borders
         ->reverse()
         ->first()
         ->name
         ->common;
```

Should return

```
Ireland
````

### Hydration

To improve performance, hydration, which is enabled by default, can be disable on most country properties, and this is how you manually hydrate properties:

```php
$countries->where('name.common', 'United States')->first()->hydrate('timezones')->timezones->first()->zone_name;

$countries->where('name.common', 'United States')->first()->hydrate('timezones')->timezones->first()->zone_name;
```

Those are some of the hydratable properties:

- Borders
- Cities
- Currencies
- Flag
- Geometry
- Languages
- States
- Taxes
- Timezone
- Topology

### Extra where rules
Some properties are stored differently and we therefore need special rules for accessing them, these properties are
- `ISO639_3` => The 3 letter language code.
- `ISO4217`  => The 3 letter currency code.

You can of course access them like other properties
```php
$countries->whereISO639_3('por')->count();
$countries->where('ISO639_3', 'por')->count();
```

### Mapping
Sometimes you would like to access a property by a different name, this can be done in settings, this way
```php
'maps' => [
    'lca3' => 'ISO639_3'
]
```
Here we bind the language 3 letter short code ISO format to `lca3`, which is short for `language code alpha 3-letter`.
So now we can access the property by
```php
$countries->whereLca3('por');
```
Or
```php
$countries->where('lca3', 'por');
```

## Some other examples from **Laravel News** and some other contributors

#### Generate a list of all countries with code, using native name and common

```php
app(PragmaRX\Countries\Package\Countries::class)
->all()
->map(function ($country) {
    $commonName = $country->name->common;

    $languages = $country->languages ?? collect();

    $language = $languages->keys()->first() ?? null;

    $nativeNames = $country->name->native ?? null;

    if (
        filled($language) &&
            filled($nativeNames) &&
            filled($nativeNames[$language]) ?? null
    ) {
        $native = $nativeNames[$language]['common'] ?? null;
    }

    if (blank($native ?? null) && filled($nativeNames)) {
        $native = $nativeNames->first()['common'] ?? null;
    }

    $native = $native ?? $commonName;

    if ($native !== $commonName && filled($native)) {
        $native = "$native ($commonName)";
    }

    return [$country->cca2 => $native];
})
->values()
->toArray();
```

Should give you 267 (or so) countries like:

## Flags

Countries provides many different flag sources, including SVG flags. This is how you use one of the available sources:

### Install [flag-icon](https://github.com/lipis/flag-icon-css)

```
npm install --save-dev flag-icon-css
```

### Import it to your project

```
@import '~flag-icon-css/sass/flag-icon.scss';
```

### Use Countries to get the flag span

```
$unitedStatesFlag =
    $this->countries->where('cca3', 'USA')
    ->first()
    ->flag
    ->flag_icon;
```

### Render it in your blade template

```
{!! $unitedStatesFlag !!}
```

## Publishing assets

You can publish configuration by doing:
```
php artisan vendor:publish --provider=PragmaRX\\Countries\\ServiceProvider
```

## Data

### Sources

This package uses some other open source packages and, until we don't build a better documentation, you can find some more info about data on [mledoze/countries](https://github.com/mledoze/countries/blob/master/README.md) and how to use it on this fantastic [Laravel News article](https://laravel-news.com/countries-and-currencies).

Please check the [copyright](#copyright) section for a complete list of packages used by this one.

### Updating

#### **WARNING** 

No data files (JSON, images, icons...) on this project can be updated manually. **We will close all pull requests requiring manual updates** to those files will be closed, because the update script will delete them anyway.

If you find something wrong with data, you, please, have to ask the package managers (listed data sources and on the copyright section) to fix them, and then you can yourself run the update script to properly update them on this repository.

#### update.php

This package comes with the `update.php` script, which you MUST use to update the data files. It will download all info from all packages and automatically build the `.json` (and some others like `.svg` too). This is how you do it:

``` bash
cd vendor/pragmarx/countries
composer install
php update.php
```

And wait for a *very long time** (sometimes it looks like stuck but it's not) until it finishes rebuilding everything, then it's just a matter of staging, commit, push all regenerated files, and draft a new PR.

## Cache

Since this data is not supposed to change, calls are automatically cached.
If you want to change this behaviour, you can edit `config/countries.php` file once it's published.
