<p>You may be trying to validate a mainnet address on a testnet/regtest client.</p>

<p>For the benefit of others:</p>

<pre><code>&lt;?php

require '/tmp/vendor/autoload.php';

$command = new \Nbobtc\Command\Command('getinfo');
$client  = new \Nbobtc\Http\Client('http://username:password@localhost:18332');

$response = $client-&gt;sendCommand($command);
$contents = $response-&gt;getBody()-&gt;getContents();

<p>I observe that bitcoin 0.18.1 will return as OP describes when attempting to validate a mainnet address on a testnet/regtest client, and return correct details otherwise.</p>

<p>If not, could you edit in to your question the actual address and the bitcoin.conf you're using.</p>

<p>Edit: I notice there IS a difference. I'm getting 
<code>{"result":{"isvalid":false},"error":null,"id":null}</code>
vs OP getting
<code>Array ( [result] =&gt; Array ( [isvalid] =&gt; ) [error] =&gt; [id] =&gt; )</code>
Perhaps there is some post-processing you're doing to $contents that is losing the value?</p>

<p>I am attempting to use Bitcoin RPC in regtest mode, however, when I try to validate a bitcoin address with the following function</p>

<p>it returns...</p>

<pre><code>Array ( [result] =&gt; Array ( [isvalid] =&gt; ) [error] =&gt; [id] =&gt; )
</code></pre>

<p>Any ideas why the isvalid value is missing?</p>

<p>I could have sworn this was working a day or two ago...</p>

# Bitcoin RPC RegTest not validating addresses

(Asked by: username_0 on 2019-09-19)

I am attempting to use Bitcoin RPC in regtest mode, however, when I try to validate a bitcoin address with the following function
public function validateAddress($address)
{
    $command = new \Nbobtc\Command\Command('validateaddress', [$address]);
    $response = $this->client->sendCommand($command);
    $contents = $response->getBody()->getContents();

    return $contents;
}

it returns...
Array ( [result] => Array ( [isvalid] => ) [error] => [id] => )

Any ideas why the isvalid value is missing?
I could have sworn this was working a day or two ago...

You may be trying to validate a mainnet address on a testnet/regtest client.
For the benefit of others:
sendCommand($command);
$contents = $response->getBody()->getContents();

echo $contents;
?>

I observe that bitcoin 0.18.1 will return as OP describes when attempting to validate a mainnet address on a testnet/regtest client, and return correct details otherwise.
If not, could you edit in to your question the actual address and the bitcoin.conf you're using.
Edit: I notice there IS a difference. I'm getting 
{"result":{"isvalid":false},"error":null,"id":null}
vs OP getting
Array ( [result] => Array ( [isvalid] => ) [error] => [id] => )
