它为你提供了什么?

这个包包含了关于国家的大量信息

地质和拓扑地图

在许多其他信息中,你可以绘制国家地图

Switzerland

要求

  • PHP 7.0+

安装

使用 Composer 安装

composer require pragmarx/countries

实例化

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();

都应该返回

€1

覆盖默认配置

use PragmaRX\Countries\Package\Services\Config;

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

用法

此包与 Laravel 无关,也不需要安装 Laravel(我们为此目的有一个 桥梁),但它在其核心中包含 Laravel Collections,所有 Collections 中的方法都可用,这样你可以进行过滤、映射、归约、搜索、排序、拒绝等操作。实际上,它使用 Coollection,这是一个具有流畅语法的 Laravel Collections,允许我们通过对象属性访问数组键(和值)。

要获取数据库中的所有国家,你只需

use PragmaRX\Countries\Package\Countries;

$countries = new Countries();

$all = $countries->all();

要获取 JSON,你

return $countries->toJson();

按键和值过滤

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

你可以通过其通用名称找到巴西,这是

#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"
      ]
    ]
  ]

或者你也可以这样过滤

$countries->whereNameCommon('Brazil');

并且,你可以更深入

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

或者通过国家顶级域名搜索

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

以获取

"name" => array:3 [▼
  "common" => "Switzerland"
  "official" => "Swiss Confederation"
  "native" => array:4 [▶]
]
"tld" => array:1 [▼
  0 => ".ch"
]

并使用像 pluck 这样的东西

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

以获取

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

该包使用一个修改过的 Collection,允许你像对象一样访问属性和方法

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

应该给出

Principality of Andorra

默认禁用边界的填充,但你可以通过调用 hydrate 方法轻松地填充边界

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

应该返回

Ireland

填充

为了提高性能,默认启用的填充可以在大多数国家属性上禁用,这是手动填充属性的方法

$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;

这些是部分可填充的属性

  • 边界
  • 城市
  • 货币
  • 国旗
  • 几何形状
  • 语言
  • 税收
  • 时区
  • 拓扑结构

额外的 WHERE 规则

某些属性以不同的方式存储,因此我们需要特殊的规则来访问它们,这些属性是

  • ISO639_3 => 3字母语言代码。
  • ISO4217 => 3字母货币代码。

当然,你可以像其他属性一样访问它们

$countries->whereISO639_3('por')->count();
$countries->where('ISO639_3', 'por')->count();

映射

有时你希望按不同的名称访问属性,这可以在设置中完成,这样

'maps' => [
    'lca3' => 'ISO639_3'
]

在这里,我们将 ISO 格式的 3 字母语言简码绑定到 lca3,即 language code alpha 3-letter 的缩写。现在我们可以通过

$countries->whereLca3('por');

$countries->where('lca3', 'por');

以下是一些来自 Laravel News 和其他贡献者的示例

生成带有代码的国家列表,使用本地名称和常用名称

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();

旗帜

国家提供许多不同的旗帜来源,包括SVG旗帜。这是如何使用可用源之一的方法

安装 flag-icon

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

将其导入到您的项目中

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

使用Countries获取旗帜span

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

在您的blade模板中渲染它

{!! $unitedStatesFlag !!}

发布资源

您可以通过以下方式发布配置

php artisan vendor:publish --provider=PragmaRX\\Countries\\ServiceProvider

数据

来源

此包使用一些其他开源包,并且在我们没有构建更好的文档之前,您可以在mledoze/countries上找到有关数据的更多信息,以及如何在Laravel News文章中使用它。

请检查版权部分以获取此包使用的所有包的完整列表。

更新

警告

此项目中的所有数据文件(JSON、图像、图标等)都无法手动更新。我们将关闭所有需要手动更新这些文件的拉取请求,因为更新脚本无论如何都会删除它们。

如果您发现数据有问题,请向包管理器(列出数据源和在版权部分)请求修复,然后您可以运行更新脚本来正确更新此存储库中的数据。

update.php

此包附带update.php脚本,您必须使用它来更新数据文件。它将从所有包中下载所有信息,并自动构建.json(以及一些其他如.svg等)。这是您如何操作的方法

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

并且等待很长时间(有时看起来像是卡住了,但实际上并没有)直到它完成所有重建,然后只需要进行暂存、提交、推送所有重新生成的文件,然后草拟一个新的PR。

缓存

由于这些数据不应更改,调用将自动缓存。如果您想更改此行为,可以在发布后编辑config/countries.php文件。
