我在逗号分隔列表中的 PHP 变量中有数据。这是数据（其中的一部分以节省空间）

$xyz="Europe, France, Italy, Spain, UK, US,Nordic, West Europe, Belgium, Luxembourg, Netherlands, Sweden,US,Asia, Europe, Israel, North America, India,North America, , China, Hong Kong,West North Central, West South Central,UK,East South Central,Middle Atlantic, Greater China, Malaysia, Singapore, Taiwan, Middle Atlantic, Global, Australasia, Central and East Europe";

我想按字母顺序排序。目前我手动执行此操作，但很乏味有没有更简单的方法可以做到这一点？

亲切的问候，艾哈迈尔

我正在向您粘贴一个片段，它在做什么：

  1. 拼接线
  2. 删除每个元素上的空格
  3. 删除空元素
  4. 排序数组
  5. 打印结果

我希望它对你有用

<?php
$xyz = "Europe, France, Italy, Spain, UK, US,Nordic, West Europe, Belgium, Luxembourg, Netherlands, Sweden,US,Asia, Europe, Israel, North America, India,North America, , China, Hong Kong,West North Central, West South Central,UK,East South Central,Middle Atlantic, Greater China, Malaysia, Singapore, Taiwan, Middle Atlantic, Global, Australasia, Central and East Europe";
$array = array_filter(array_map('trim', explode(',', $xyz)));
asort($array);
$array = implode(', ', $array);
print_r($array);

试试这个：

$xyz="Europe, France, Italy, Spain, UK, US,Nordic, West Europe, Belgium, Luxembourg, Netherlands, Sweden,US,Asia, Europe, Israel, North America, India,North America, , China, Hong Kong,West North Central, West South Central,UK,East South Central,Middle Atlantic, Greater China, Malaysia, Singapore, Taiwan, Middle Atlantic, Global, Australasia, Central and East Europe";

$arr = explode(',', $xyz);
asort($arr);
print_r($arr);

// break apart the string at each comma
$parts = explode(',',$xyz);

// create an array
$array = array();

// loop through $parts and put each country into the new array
foreach($parts as $part) {
    array_push($array,$part);
}

// sort the array alphabetically
asort($array);

print_r($array);

使用explode：

$xyz_arr = explode(',', $xyz);
sort($xyz_arr);

我的答案部分基于@Carlos 的答案，但在这里和那里进行了一些调整，并包装成一个可重用的函数。它应该有能力完成工作，对吧！

/* A global function to sort a [STRING] comma-delimited list both alphabetically, and numerically, and then return the sorted [STRING] list back to the function caller. [BEGIN] */

if (!function_exists('sortCommaDelimitedListStr'))
    {
        function sortCommaDelimitedListStr($var)
            {
                $arr = array_filter(array_map('trim', explode(',', $var)));
                sort($arr);
                $arr = implode(', ', $arr);
                return $arr;
            };
    };

/* A global function to sort a [STRING] comma-delimited list both alphabetically, and numerically, and then return the sorted [STRING] list back to the function caller. [END] */

要使用，只需像这样调用函数：

$xyz = "Europe, France, Italy, Spain, UK, US,Nordic, West Europe, Belgium, Luxembourg, Netherlands, Sweden,US,Asia, Europe, Israel, North America, India,North America, , China, Hong Kong,West North Central, West South Central,UK,East South Central,Middle Atlantic, Greater China, Malaysia, Singapore, Taiwan, Middle Atlantic, Global, Australasia, Central and East Europe";

$xyz = sortCommaDelimitedListStr($xyz);

  1. 首先使用explode 函数来分解逗号上的字符串。
  2. 使用 array_map() 函数删除空格。
  3. 使用 asort() 函数按升序对数组进行排序。
  4. 然后使用 implode() 将数组转换为字符串。


$xyz="Europe, France, Italy, Spain, UK, US,Nordic, West Europe, Belgium, Luxembourg, Netherlands, Sweden,US,Asia, Europe, Israel, North America, India,North America, , China, Hong Kong,West North Central, West South Central,UK,East South Central,Middle Atlantic, Greater China, Malaysia, Singapore, Taiwan, Middle Atlantic, Global, Australasia, Central and East Europe";


$xyz = explode(',',$xyz);
$trimSpaces = array_map('trim',$xyz);
asort($trimSpaces);
$xyz = implode(',',$trimSpaces);
print_r($xyz);
