中文怎么转换为bytes[]

[hongmei85]

例如“广东” 转化成byte[]={[-27, -71, -65, -28, -72, -100]}

用一个现成的函数还是要稍微编个函数

[xuzuning]

var b = Encoding.UTF8.GetBytes("广东");
Console.WriteLine(string.Join(",", b));

229,185,191,228,184,156 Byte 是无符号整型，如果你一定要负数的话就每项减 256

求直接的php代码，临时用，以后再仔细研究

[xuzuning]

$s = "广东";
$s = iconv('gbk', 'utf-8', $s);
$r = array_map('ord', str_split($s));
print_r($r);

Array
(
    [0] => 229
    [1] => 185
    [2] => 191
    [3] => 228
    [4] => 184
    [5] => 156
)

或

$s = "广东";
$s = iconv('gbk', 'utf-8', $s);
$r = unpack('C*', $s);
print_r($r);

Array
(
    [1] => 229
    [2] => 185
    [3] => 191
    [4] => 228
    [5] => 184
    [6] => 156
)

或

$s = "广东";
$s = iconv('gbk', 'utf-8', $s);
$r = unpack('c*', $s);
print_r($r);

Array
(
    [1] => -27
    [2] => -71
    [3] => -65
    [4] => -28

    [6] => -100
)
