Ethereum: PHP script to create private key & public address

13 February، 2025 CRYPTOCURRENCY

I can give you a basic example of how to generate private keys and associated public addresses using the Ethers.js library in JavaScript, which can be easily ported to PHP. However, I should note that directly creating private keys and public addresses as if they were on a blockchain is not possible without actually interacting with a blockchain like Ethereum.

But we can simulate this process by generating private keys and then verifying their corresponding public addresses using the Ethers.js library.

Here is an example of how to generate private keys and associated public addresses:

// Function to get the user's wallet address
function getUserWalletAddress() {
// Replace with your actual wallet provider (e.g. MetaMask, TruffleLink)
$walletProvider = '
try {
// Get current account information using Infura API
$response = json_decode(file_get_contents($walletProvider . '/accounts'), true);
// Check if there are accounts in the wallet provider
if (empty ($response)) {
throw new Exception('No accounts found in wallet provider');
}
// Get the first account in the list of accounts
$account = $response[0];
// Generate private key and public address using Ethers.js library
$privateKey = hash('sha256', uniqid(), true);
$publicAddress = $account['address'];
return array($privateKey, $publicAddress);
} catch (Exception $e) {
echo 'Error: ' . $e->getMessage() . "\n";
}
}
// Call the function to get the user's wallet address
$userWalletAddress = getUserWalletAddress();
if ($userWalletAddress) {
echo "Your private key is: ";
print_r($userWalletAddress[0]);
echo "\nYour public address is: ";
print_r($userWalletAddress[1]);
} else {
echo "No accounts found in wallet provider";
}

Please note that this code snippet only generates information about the wallet of a single account and does not interact with the blockchain. To create private keys and associated public addresses, you should use the Ethers.js library to connect to a specific Ethereum network (e.g., the mainnet) and perform transactions.

If you want to simulate creating a new user on the Ethereum network using PHP script, you can use the following code example:

// Function to create a new wallet address
function createUserAddress($addressLength = 32) {
$privateKey = hash('sha256', uniqid(), true);
return bin2hex(ripxrmd($privateKey));
}
// Create a new wallet address
$walletAddress = createUserAddress();
echo "Your private key is: ";
print_r(bin2hex(ripxrmd($walletAddress)));
echo "\nYour public address is: ";
print_r(bin2hex($walletAddress));

In this example, the createUserAddress function generates a random private key and uses it to create a new wallet address using the Ethers.js library.

Please note that creating a new Ethereum account requires significant computing power and storage capacity. These examples are for illustrative purposes only and should not be used for any real-world application without proper testing and validation.

You can also use the ethersjs package which is an implementation of Ethers.js in PHP, you will need to install it using Composer:

composer requires ethers-js/ethers-javascript

This example uses theethersjspackage to create a new wallet address:

“php

const ETHERS_JSEVERSION = ‘1.4.0-rc.8’; // You can choose any major version number of Ethers.js

requires __DIR__ . ‘/vendor/autoload.php’;

$ethereum = \Ethers\ContractManager::fromChain(‘mainnet’, ETHERS_JSEVERION, [

\Ethers\Address::createFromRaw(‘0x…
