PHP Equivalent to C# GetBytesFromUTF8_问答_开发者

I am trying to create a php function thats will allow me access to a dotnet single sign on system and I am hung up on finding a php equivalent to GetBytesFromUTF8, I have tried ord and mb_string to no avail. Any ideas for a php equivalent to the C# GetBytesFromUTF8?

//Function to Create the SSO function SSO($key,$uid){ $lenth=32; $aZ09 = array_merge(range('A', 'Z'), range('a', 'z'),range(0, 9)); $randphrase ='';

        for($c=0;$c < $lenth;$c++) {
           $randphrase .= $aZ09[mt_rand(0,count($aZ09)-1)];
        } 
        //Append key onto phrase end
        $randkey=$randphrase.$key;
        //Number of Bytes is string  (THIS IS THE PROBLEM, ITS JUST ADDING THE STRING LENGTH)
        $bytevalue=mb_strlen($randkey, 'latin1');
        // SHA512 Hash
        //$toencode= utf8_encode($bytevalue);
        $output = hash("sha512", $bytevalue);
        //base 64 encode the hash
        $sso = base64_encode($output);
        $length = mb_strlen($sso);
        $characters = 2;
        $start = $length - $characters;
        $last2 = substr($sso , $start ,$characters); 
        //$startitup = APIClient::Create('http://my.staging.dosespot.com/LoginSingleSignOn.aspx','SingleSignOnCode=$ssocode');
        // Yes, Strip the extra ==
        if($last2 == "=="){$ssocode = substr($sso,0,-2);}
        // No, just pass the value to the next step
        else{$ssocode=$sso;}

        //Use first 22 charecters of random.
        $shortphrase=substr($randphrase,0,22);
        //Append uid & key onto shortened phrase end
        $uidv=$uid.$shortphrase.$key;
        //Number of Bytes is string
        $idbytevalue=mb_strlen($uidv, 'latin1');
        //$idbytevalue= strBytes(utf8_encode($uidv));

I am trying to replicate this C# process in PHP to no avail. HOW TO CREATE THE CORRECT SINGLESIGNONCODE: 1. You have been provided a key (in UTF-8) 2. Create a random phrase 32 characters long in UTF-8 a. Create32CharPhrase 3. Append the key to the phrase a. Create32CharPhrase + Key 4. Get the value in Bytes from UTF-8 String a. GetBytesFromUTF8(Create32CharPhrase + Key) 5. Use SHA512 to hash the byte value you just received SHA512Hash(GetBytesFromUTF8(Create32CharPhrase + Key)) 6. Get a Base64String out of the hash that you created GetBase64String(SHA512Hash(GetBytesFromUTF8(Create32CharPhrase + Key))) 7. If there are two = signs at the end, then remove them. RemoveExtraEqualsSigns(GetBase64String(SHA512Hash(GetBytesFromUTF8(Create32CharPhrase + Key))))

The Second part of the function...

HOW TO CREATE THE CORRECT SINGLESIGNONUSERIDVERIFY: 1. Grab the first 22 characters of the phrase from step 1 2. Append to the UserId string the 22 characters grabbed from step one 3. (UserId) + (first 22 characters of phrase) 4. Append the key to the string created in 2b (UserId) +(first 22 characters of phrase) + key 5. Get the Byte value of the string GetBytesFromUTF8((UserId) + (first 22 characters of phrase) + key) 6. Use SHA512 to hash the byte value you just received SHA512Hash(GetBytesFromUTF8((UserId) + (first 22 characters of phrase) + key)) 7. Get a Base64String out of the hash that you created 8. GetBase64String(SHA512Hash(GetBytesFromUTF8((UserId) + (first 22 characters of phrase) + key))) 9. If there are two = signs at the end, then remove them. RemoveExtraEqualsSigns(GetBase64String(SHA512Hash(GetBytesFromUTF8((UserId) + (first 22 characters of phrase) + key))))
