Hey,
I am using this code on one of my vps
Code:

<?php
require_once('easybitcoin.php');
$bitcoin = new Bitcoin('uname','password','node_ip','port');
$new=$bitcoin->status;
var_dump($new);
var_dump($bitcoin);
?>



I am getting this everytime:

Code:
NULL
object(Bitcoin)#1 (12) { ["username":"Bitcoin":private]=> string(12) "uname" ["password":"Bitcoin":private]=> string(18) "password" ["proto":"Bitcoin":private]=> string(4) "http" ["host":"Bitcoin":private]=> string(12) "node_ip" ["port":"Bitcoin":private]=> string(4) "8392" ["url":"Bitcoin":private]=> NULL ["CACertificate":"Bitcoin":private]=> NULL ["status"]=> NULL ["error"]=> NULL ["raw_response"]=> NULL ["response"]=> NULL ["id":"Bitcoin":private]=> int(0) }


Here's the bitcoin.conf from the node:

Code:

prune=600
maxconnections=12
maxuploadtarget=20
server=1
rpctimeout=30

rpcallowip=VPS IP
rpcport=8392
rpcuser=uname
rpcpassword=passwrd

daemon=1


Any help will be appreciated, thanks!

easybitcoin seems to be no longer working, or needs some tweaking.

I have written a php function using curl.
You can use this php function, if you are also looking for a solution:
Just pass the method in the function and make sure to edit out your rpc details inside the function.

Code:
<?php

function bitcoin($method){
$ch curl_init();
$rpcuser='rpcusername';
$rpcpassword='rpcpassword'
$host='nodeIP';  //IP address of your node or localhost, if running locally
$port='port';

curl_setopt($chCURLOPT_URL"http://$rpcuser:$rpcpassword@$host:$port/");
curl_setopt($chCURLOPT_RETURNTRANSFER1);
curl_setopt($chCURLOPT_POSTFIELDS"{\"jsonrpc\":\"1.0\",\"id\":\"curltext\",\"method\":\"$method\",\"params\":[]}");
curl_setopt($chCURLOPT_POST1);

$headers = array();
$headers[] = "Content-Type: application/x-www-form-urlencoded";
curl_setopt($chCURLOPT_HTTPHEADER$headers);

$result curl_exec($ch);
if (
curl_errno($ch)) {
    echo 
'Error:' curl_error($ch);
}
curl_close ($ch);
return(
$result);
}
$method="getblockchaininfo"//bitcoin-cli method like getchaininfo,getwalletinfo etceter
$lol=bitcoin($method);
?>



Cheers!

You can use JSON RPC CLIENT:
