国家

它能给你什么？

这个包包含了有关国家的各种信息

地质和拓扑地图

在众多其他信息中，您还可以绘制国家地图

要求

• PHP 7.0+

安装

使用 Composer 安装它

composer require pragmarx/countries

实例化

use PragmaRX\Countries\Package\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();

应同时返回

€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,
        ],
    ],
]));

使用

此包在其核心中包含 Laravel Collections，Collections 中的所有方法都可用，这样您就可以执行过滤、映射、归约、搜索、排序、拒绝等操作。它实际上使用了 Coollection，这是一个具有流畅语法的 Laravel Collections，使我们能够将数组键（和值）作为对象属性访问。

要获取数据库中的所有国家，只需

use PragmaRX\Countries\Package\Countries;

$countries = new Countries();

$all = $countries->all();

要获取 JSON，您

return $countries->toJson();

通过键和值过滤

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

可以通过其通用名称找到巴西，这是一个

#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"
      ]
    ]
  ]

或者您也可以这样过滤

$countries->whereNameCommon('Brazil')

并且，您可以进一步深入

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

或者通过国家顶级域名搜索

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

要获取

"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')

要获取

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

该包使用了一个修改后的 Collection，允许您将属性和方法作为对象访问

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

应给出

Principality of Andorra

默认禁用边界水合，但您可以通过调用 hydrate 方法轻松地使边界水合

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

应返回

Ireland

水合

为了提高性能，默认启用的水合可以在大多数国家属性上禁用，这就是您手动水合属性的方法

$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,

以下是一些可水合的属性

• 边界
• 城市
• 货币
• 国旗
• 几何
• 语言
• 州
• 税收
• 时区
• 拓扑

额外的 WHERE 规则

一些属性存储方式不同，因此我们需要特殊规则来访问它们，这些属性是

• ISO639_3 => 3个字母的语言代码。
• ISO4217 => 3个字母的货币代码。

当然，您可以通过其他属性访问它们

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

映射

有时您希望通过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 格式的语言 3 位短代码与 lca3 绑定，它是 language code alpha 3-letter 的缩写。现在我们可以通过以下方式访问属性

$countries->whereLca3('por')

或者

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

以下是一些来自 Laravel News 和其他贡献者的示例

使用代码生成所有国家的列表，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();

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

将其导入到您的项目中

    ->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

此软件包使用一些其他开源软件包，直到我们构建更好的文档，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。

缓存

由于这些数据不应更改，调用会自动缓存。如果您想更改此行为，一旦发布，可以编辑config/countries.php文件。
