如何在PHP中拆分中文字符？

Question

关于如何在PHP中分割混有英文单词和数字的汉字,我需要一些帮助.

例如,如果我读

FrontPage 2000???????

我希望得到

FrontPage, 2000, ?,?,?,?,?,?,?

要么

FrontPage, 2,0,0,0, ?,?,?,?,?,?,?

我怎样才能做到这一点？

提前致谢 :)

假设您正在使用UTF-8(或者您可以使用Iconv或其他工具将其转换为UTF-8),那么使用u修饰符(doc:http://www.php.net/manual/en/reference.pcre. pattern.modifiers.php)

<?
$s = "FrontPage 2000???????";
print_r(preg_match_all('/./u', $s, $matches));
echo "\n";
print_r($matches);
?>

会给

21
Array
(
    [0] => Array
        (
            [0] => F
            [1] => r
            [2] => o
            [3] => n
            [4] => t
            [5] => P
            [6] => a
            [7] => g
            [8] => e
            [9] =>  
            [10] => 2
            [11] => 0
            [12] => 0
            [13] => 0
            [14] => ?
            [15] => ?
            [16] => ?
            [17] => ?
            [18] => ?
            [19] => ?
            [20] => ?
        )

)

请注意,我的源代码也存储在以UTF-8编码的文件中,$ s包含这些字符.

以下内容将字母数字作为一组匹配:

<?
$s = "FrontPage 2000???????";
print_r(preg_match_all('/(\w+)|(.)/u', $s, $matches));
echo "\n";
print_r($matches[0]);
?>

结果:

10
Array
(
    [0] => FrontPage
    [1] =>  
    [2] => 2000
    [3] => ?
    [4] => ?
    [5] => ?
    [6] => ?
    [7] => ?
    [8] => ?
    [9] => ?
)
