* @return string 转换后的数组
*/
function strToArray($string) {
$strlen = mb_strlen($string);
while ($strlen) {
$array[] = mb_substr($string, 0, 1, "utf8");
$string = mb_substr($string, 1, $strlen, "utf8");
$strlen = mb_strlen($string);
}
return $array;
}
用法：$string = '这里就是要转换成数组的字符串，';
$arr = strToArray($string);
print_r($arr);
输出：Array
