PHP chunk_split()问题

Question

当我使用chunk_split()函数时,它会破坏我的口音字符和特殊字符,我想知道如何纠正这个问题？

这是我的PHP代码.

if(count($text) > 0) {
    $text = implode(' ', $text);
    echo chunk_split($text, 8, '<br />'); 
}

被破坏的重音字符.

chunk_split不是多字节安全的,并且没有本机mb_chunk_split.

这是一个从php文档中的评论者那样做的功能:

<?php

//from Peter from dezzignz.com 05-Apr-2010 11:30 @ php.net

function mbStringToArray ($str) {
    if (empty($str)) return false;
    $len = mb_strlen($str);
    $array = array();
    for ($i = 0; $i < $len; $i++) {
        $array[] = mb_substr($str, $i, 1);
    }
    return $array;
}

function mb_chunk_split($str, $len, $glue) {
    if (empty($str)) return false;
    $array = mbStringToArray ($str);
    $n = 0;
    $new = '';
    foreach ($array as $char) {
        if ($n < $len) $new .= $char;
        elseif ($n == $len) {
            $new .= $glue . $char;
            $n = 0;
        }
        $n++;
    }
    return $new;
}

?>
