如何将多字节字符串拆分为Php中的单词? 这是我到目前为止所做的,但我想改进代码......

   mb_internal_encoding( 'UTF-8');
   mb_regex_encoding( 'UTF-8');
   $arr = mb_split( '[\s\[\]().,;:-_]', $str );

有没有办法说是一系列“alpha”字符(不使用符号a-z,因为我想包含非拉丁字符)

在这里试试这个宝宝:

preg_match_all('/[\p{L}\p{M}]+/u', $subject, $result, PREG_PATTERN_ORDER);
for ($i = 0; $i < count($result[0]); $i++) {
    # Matched text = $result[0][$i];
}

将所有可能的字母与其重音符号匹配为:

     "
[\p{L}\p{M}]       # Match a single character present in the list below
                   # A character with the Unicode property “letter” (any kind of letter from any language)
                   # A character with the Unicode property “mark” (a character intended to be combined with another character (e.g. accents, umlauts, enclosing boxes, etc.))
   +               # Between one and unlimited times, as many times as possible, giving back as needed (greedy)
"

<强> See it.

许多语言不使用单词(中文)。在这种情况下函数应该返回整个字符串吗?在PHP中,explode()是二进制安全的,因此如果您只需要一个分隔符,那么使用它可能会更快。

也许您应该使用\w吗?
