Laravel / PHP 语言代码排序

Question

我的数据库中存储了一些语言，如下所示：

id | code  | name 
--------------------------------------
1  | en_GB | English, United Kingdom
2  | pt_BR | Portugese, Brazil
3  | it_IT | Italian, Italy
4  | hi_IN | Hindi, India
5  | es_BR | Spanish, Brazil
6  | ur_IN | Urdu, India

我想获取这些结果并进行排序（或在获得所有结果后进行排序），因此我首先按排序的国家代码（代码的第二部分）然后按区域设置代码（代码的第一部分）获得结果，所以：

$languages = [
    0 => [
       'code' => 'es_BR'
    ],
    1 => [
       'code' => 'pt_BR'
    ],
    2 => [
       'code' => 'en_GB'
    ],
    3 => [
       'code' => 'hi_IN'
    ],
    4 => [
       'code' => 'ur_IN'
    ],
    5 => [
       'code' => 'it_IT'
    ]
];

我尝试遍历每种语言并取出第二部分并存储国家代码数组，然后使用asort($countryCodes); 对它们进行排序，它按国家代码 (GB) 排序，但我无法排序按区域设置代码 (en) 列出。

任何帮助将不胜感激，谢谢！

Answer 1

我想出了以下内容，它给了我我需要的东西：

$languages = $this->getOrderedLanguages();

protected function getOrderedLanguages() 
{
    $languages = Language::orderBy('code')->get();

    // Sort out the other languages by country code (e.g. sort by GB in code en_GB)
    // Create array for each country code and store array key from original list
    $countryCodes = [];
    foreach($languages as $key => $language) {
        $countryCodes[$language->locale_code][] = [
            'id' => $key,
            'language' => $language->language_code
        ];
    }
    ksort($countryCodes);

    $orderedLanguages = [];

    // Go through each country code and sort the languages in there by locale code (e.g. sort by en in code en_GB)
    foreach($countryCodes as &$countryCode) {
        asort($countryCode);
        foreach($countryCode as $language) {
            $orderedLanguages[] = $allLanguages[$language['id']];
        }
    }

    // Return ordered array
    return $orderedLanguages;
}

这给了我以下结果：

$languages = [
    0 => [
        'code' => 'es_BR'
    ],
    1 => [
        'code' => 'pt_BR'
    ],
    2 => [
        'code' => 'en_GB'
    ],
    3 => [
        'code' => 'hi_IN'
    ],
    4 => [
        'code' => 'ur_IN'
    ],
    5 => [
        'code' => 'it_IT'
    ]
];

Answer 2

我猜array_multisort 就是你要找的。​​p>

Answer 3

你会使用 usort() - http://php.net/usort

我的建议是：

function cmp($a, $b){
    return strcmp($a["code"], $b["code"]);
}

usort($languages, "cmp");
print_r($languages);

希望对你有帮助

Answer 4

请尝试其他版本的代码：

$fArray=array();
foreach($languages as $languages){
   array_push($fArray,$languages);
}
sort($fArray);
print_r($fArray);  

`OR`

array_multisort($languages);
print_r($languages);

以下是为这两个函数生成的数组：

Array
(
 [0] => Array
    (
        [code] => en_GB
    )

[1] => Array
    (
        [code] => es_BR
    )

[2] => Array
    (
        [code] => hi_IN
    )

[3] => Array
    (
        [code] => it_IT
    )

[4] => Array
    (
        [code] => pt_BR
    )

[5] => Array
    (
        [code] => ur_IN
    )

)
