怎么写？

回复讨论(解决方案)

$s = '中文abc';$s = iconv('gbk', 'utf-8', $s); //不是 utf-8 时需转 utf-8print_r(unpack('C*', $s));

Array(    [1] => 228    [2] => 184    [3] => 173    [4] => 230    [5] => 150    [6] => 135    [7] => 97    [8] => 98    [9] => 99)

C#测试

            foreach (var c in UTF8Encoding.UTF8.GetBytes("中文abc"))            {                Console.WriteLine(c);            }

$s = '中文abc';$s = iconv('gbk', 'utf-8', $s); //不是 utf-8 时需转 utf-8print_r(unpack('C*', $s));
