PHP Minecraft second-account?

Is there any way I can get through PHP all second and third accounts and more out?

Define your question more precisely

Your own multiaccounts or the accounts of others?

The accounts of others

That does not work so easily. Besides, I have no idea how to get to PHP, what does that have to do with it? Also. How should the script recognize because it is second or third accounts?

If it were that easy, MC's online service could finally be taken offline. You need some understanding to dump accounts etc.

It's not about dumping ACC's! I just want to know which player has which accounts!

I believe the exact application is not clear from your question… What data do you have and what do you want?

If you have UUIDs and IP addresses, you might associate accounts like that, if that's what you mean. What exactly you want to do with PHP I do not realize.
