title: How to generate Ethereum wallets(private/public keys) for users using PHP/JS?
body: <p>I need to generate Ethereum wallets for each user of my site. I need to get private and public keys. How to do it using PHP or Javascript?<br>
  For Ethereum I found web3.js library which I can use for getting access to an ethereum nodes, but I see examples only for checking balances or sending transactions for existed wallets. How to create them from begging with no private/public keys at all?</p>
