Just a quick piece of code, that is using Bitwasp library to mare redeem script from private key
<?php |
require __DIR__ . "/vendor/autoload.php"; |
use BitWasp\Bitcoin\Key\Factory\PrivateKeyFactory; |
use BitWasp\Bitcoin\Script\ScriptFactory; |
// Private key for address |
$wifkey='privatekeycomeshere'; |
// Initializing Private Key Class |
$privKeyFactory = new PrivateKeyFactory(); |
// Getting private key from the one stored in WIF format |
$key = $privKeyFactory->fromWif($wifkey); |
$redeemScript = ScriptFactory::scriptPubKey()->p2wkh($key->getPubKeyHash()); |
print_r($redeemScript); |
?> |
