我有个字符串,格式为$str = "中华人民abc共和\x01国",如何逐个汉字遍历该字符串呢?即:能够输出“中” “华” “人” “民” “a” ...

我现在使用的方法是:for($i =0 ; $i

请问应该如何提高效率?是否可以讲$str转换为数组?

<code class="lang-php">function str_split_unicode($str, $l = 0) {
if ($l > 0) {
$ret = array();
$len = mb_strlen($str, "UTF-8");
for ($i = 0; $i  中
    [1] => 华
    [2] => 人
    [3] => 民
    [4] => a
    [5] => b
    [6] => c
    [7] => 共
    [8] => 和
    [9] => \
    [10] => x
    [11] => 0
    [12] => 1
    [13] => 国
)

//UTF8算法,其它编码自行转换

<code class="lang-php"><br> $cind = 0;
 $arr_cont = array();
 for ($i = 0; $i  0) {
                if (ord(substr($tempaddtext, $cind, 1)) </code>
