方法一：

$str = "abc";
$key = "310A54B3C9C12920E1582E016F15DD441ACE8553769E8991";
$decodedKey = pack("H*", $key);  //十六进制转成字符串
$hash = bin2hex(hash_hmac("sha1", $str, $decodedKey, true));

　　

方法二：

//字节数组转化为String类型的数据
function toStr($bytes) {
    $str = '';
    foreach($bytes as $ch) {
        $str .= chr($ch);
    }
    return $str;
}
//字符串转十六进制
function String2Hex($string){
    $hex='';
    for ($i=0; $i < strlen($string); $i++){
        $hex .= dechex(ord($string[$i]));
    }
    return $hex;
}

//十六进制转字符串
function Hex2String($hex){
    $string='';
    for ($i=0; $i < strlen($hex)-1; $i+=2){
        $string .= chr(hexdec($hex[$i].$hex[$i+1]));
    }
    return $string;
}

$str = "abc";
$key = "310A54B3C9C12920E1582E016F15DD441ACE8553769E8991";
$decodedKey = pack("H*", $key);  //十六进制转字符串
$hash = hash_hmac("sha1", $str, $decodedKey, true);
//字符串转字节数组，即ascii数组
$hashs = str_split($hash);
foreach ($hashs as $index => $value) {
    if (ord($value) > 128) {
        $hashs[$index] = ord($value) - 128 * 2;
    } else {
        $hashs[$index] = ord($value);
    }
}
$signature = String2Hex(toStr($hashs));
echo $signature;
