This is a handy guide to get your SPC from your ESN if you have a 10 digit calculator (and a sheet of paper to write down the variables; I've never trusted the memory buttons myself). You can also do this out by hand if you want. Just don't forget the additional numbers these equations call for, especially on the longer step 3. Enjoy!

1. Imagine breaking apart the ESN into 11 separate numbers, #1-#11.
Let's use the example ESN of 12345678901. This means we have 1,2,3,4,5,6,7,8,9,0, and 1.

2. Do the following equations; (X=)#1+#2+#3+5. 2^X. X-1. Keep this result as X.
Ok, then 1+2+3+5 = 11. Then 2^11 = 2048. Then 2048-1 = 2047 = X.

3. Do the next equation; #4+#5+#6+#7+#8+#9+#10+#11+23. Keep this result as Y.
Now we get 4+5+6+7+8+9+0+1+23 = 63 = Y.

4. Add the last 3 digits of your ESN to 199 (#9#10#11+199). Keep this result as Z.
901+199 = 1100 = Z.

5. X*Y*Z.
2047*63*1100 = 141857100

6. The last 6 digits of the resulting number is your SPC.
We can easily count over to get 857100. This also checks with previous results.

The compressed guide that'll fit on a small index card;
1. X= #1 +#2 +#3 +5, 2^X, X-1.
2. Y= #4 +#5 +#6 +#7 +#8 +#9 +#10 +#11 +23.
3. Z= String #9 #10 #11, +199.
4. X*Y*Z, SPC is last 6.

PS. By the way, you might get a 10 digit number in step 5. Don't get all hasty with your lightbulb that might go off about the 10 digit code we still need. Many other people get 9 digits, and I figure there are even those that get 11 digits. However, if you do get a 10 digit code and it does work as the code, PM me immediately. You are probably 1 in 10 billion and someone else needs to verify that it works on another Fin.

I don't think anyone is going to trust it. Why not just build a javascript one instead?

I made the XLS file in the other topic. Lol. It does the same thing as this topic, exactly. It is no different. This is essentially a human readable port of that code so anyone can use it in any way they please.

However, your PHP question. The only way to do that is to make a SMF forum package that uses client-side code and maybe have it part of the user's profile or something. I might could install the package, but I'm not a SMF guru. I'd probably have some trouble getting it going, most assuredly.

You might want to change this to inequality (!=) rather than a simple less than. I'll keep looking. Are you still working on the PHP script?

Thank You Nice-Man!! As per your request, i am now hosting it!

Your code is intact, i just cleaned up the HTML a little
