Topic: [PHP] How to get the address from a private key? (Read 1272 times)
How can I calculate the public address if I only have the private key with PHP only?
For example I have
5K2YUVmWfxbmvsNxCsfvArXdGXm7d5DC9pn4yD75k2UaSYgkXTh
and want

Does anyone have a working PHP code without using bitcoind or any other API/tools?

Well you can use a ready PHP library to do this , I didn't ever saw how it work and how Bitcoin address are hashed !
You can check this library and you will probably understand how it work and make your own ` easy code ` .

Hello, alex1s,
We had almost the same issue and we used the following answer on stackoverflow
http://stackoverflow.com/questions/19233053/hashing-from-a-public-key-to-a-bitcoin-address-in-php
However we do not know its behaviour in a case of multiple senders. For example if you need to retrieve the addresses of those, who sent you some coins, f.ex using walletnotify.

A lot will depend on what PHP extensions you have installed on your server. If you're on shared hosting (like many are) your hosting provider controls what version of PHP is ran and which extensions. Echo out phpinfo(); to see what you have installed. Ones that I have seen you'll need bcrypt, bmath, and an ECC library as well. So I usually just end up using a 3rd party API to do key generation.
Maybe give this one a try, it doesn't have many requirements.

Maybe try this source on gitHub: https://github.com/RobKohr/PHP-Bitcoin-Address-Creator or http://gobittest.appspot.com/Address
It really depends on what you are asking, but this may be useful:

just import the private key into your wallet , and you've got the public key. For example I have
