    from:http://blog.csdn.net/ciaos/article/details/12618487

    PHP代码示例如下

     <?php

            $res1 = hash_hmac("sha1","signatureString""secret");
            echo $res1." ";
            //ee1b654aa861c41fd5813dc365ef106c9801f8f6
            echo base64_encode($res1)." ";
            //ZWUxYjY1NGFhODYxYzQxZmQ1ODEzZGMzNjVlZjEwNmM5ODAxZjhmNg==

            $res2 = hash_hmac("sha1","signatureString""secret"true);
            //echo "$res2 ";//binary byte[]
            $data = unpack('C*', $res2);
            print_r($data);
            /*
            Array
            (
                [1] => 238
                [2] => 27
                [3] => 101
                [4] => 74
                [5] => 168
                [6] => 97
                [7] => 196
                [8] => 31
                [9] => 213
                [10] => 129
                [11] => 61
                [12] => 195
                [13] => 101
                [14] => 239
                [15] => 16
                [16] => 108
                [17] => 152
                [18] => 1
                [19] => 248
                [20] => 246
            )

            
    */

            echo base64_encode("$res2 ");
            //7htlSqhhxB/VgT3DZe8QbJgB+PYK
