将utf8字符串拆分为字符数组 [英] Split utf8 string into array of chars

问题描述

我正在尝试将 utf8 编码的字符串拆分为字符数组.我现在使用的功能曾经可以使用，但是由于某种原因它不再起作用了.可能是什么原因.而且更好的是，我该如何解决?

I'm trying to split a utf8 encoded string into an array of chars. The function that I now use used to work, but for some reason it doesn't work anymore. What could be the reason. And better yet, how can I fix it?

这是我的字符串:

Zelf heb ik maaréénvraag:wie ben jij?

Zelf heb ik maar één vraag: wie ben jij?

这是我的功能:

function utf8Split($str, $len = 1)
{
  $arr = array();
  $strLen = mb_strlen($str);
  for ($i = 0; $i < $strLen; $i++)
  {
    $arr[] = mb_substr($str, $i, $len);
  }
  return $arr;
}

这是结果:

Array
(
    [0] => Z
    [1] => e
    [2] => l
    [3] => f
    [4] =>  
    [5] => h
    [6] => e
    [7] => b
    [8] =>  
    [9] => i
    [10] => k
    [11] =>  
    [12] => m
    [13] => a
    [14] => a
    [15] => r
    [16] =>  
    [17] => e
    [18] => ́
    [19] => e
    [20] => ́
    [21] => n
    [22] =>  
    [23] => v
    [24] => r
    [25] => a
    [26] => a
    [27] => g
    [28] => :
    [29] =>  
    [30] => w
    [31] => i
    [32] => e
    [33] =>  
    [34] => b
    [35] => e
    [36] => n
    [37] =>  
    [38] => j
    [39] => i
    [40] => j
    [41] => ?
)

推荐答案

我发现é不是我期望的字符.显然，né和ńe之间是有区别的.我首先通过规范化字符串来使它工作.

I found out the é was not the character I expected. Apparently there is a difference between né and ńe. I got it working by normalizing the string first.
