我怎么能进行排序PHP中的UTF-8字符串？

问题描述：

需要由UTF-8排序的话帮助。例如，我们有5个城市来自比利时。

need help with sorting words by utf-8. For example, we have 5 cities from Belgium.

$array = array('Borgloon','Thuin','Lennik','Éghezée','Aubel');
sort($array); // Expected: Aubel, Borgloon, Éghezée, Lennik, Thuin
              // Actual: Aubel, Borgloon, Lennik, Thuin, Éghezée

市埃格泽应该是第三个。是否有可能使用/设置某种UTF-8或创建自己的字符顺序？

City Éghezée should be third. Is it possible to use/set some kind of utf-8 or create my own character order?

答

国际捆绑从PHP 5.3和PHP 只支持UTF-8 。

intl comes bundled with PHP from PHP 5.3 and it only supports UTF-8.

您可以在此情况下，使用分页器：

You can use a Collator in this case:

$array = array('Borgloon','Thuin','Lennik','Éghezée','Aubel');
$collator = new Collator('en_US');
$collator->sort($array);
print_r($array);

输出：

Array
(
    [0] => Aubel
    [1] => Borgloon
    [2] => Éghezée
    [3] => Lennik
    [4] => Thuin
)
