i found one solution and seems its working

install phpseclib via composer

composer require phpseclib/phpseclib
use phpseclib\Crypt\RSA as Crypt_RSA;

$rsa = new Crypt_RSA();
$rsa->loadKey($publickey);
$rsa->setEncryptionMode(2);
$data = 'Your String';
$output = $rsa->encrypt($data);
echo base64_encode($output);
