PHP converts a string into an array, supports Chinese

/**
 * 将一个字符串转换成数组,支持中文
 * @param string    $string   待转换成数组的字符串
 * @return string   转换后的数组
 */
function strToArray($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;
}


Usage:

$string = '这里就是要转换成数组的字符串,www.liqingbo.cn';
$arr = strToArray($string);
print_r($arr);
