bitcoin PHP json rpc error "JSON value is not an integer as expected"

i am trying to connect to my local bitcoind using php json library https://github.com/aceat64/EasyBitcoin-PHP specified in https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)#PHP

i am trying to get block data. e.g.

Code:

$bitcoin = new Bitcoin('user','password');
$blockhash = $bitcoin->getblockhash('502284') ;

i am getting

JSON value is not an integer as expected

on further debuggng

$curl_error = curl_error($curl);

Code:

(
    [result] =>
    [error] => Array
        (
            [code] => -1
            [message] => JSON value is not an integer as expected
        )

    [id] => 1
)

this happens only with blockheight 502284 and not with other blocks.,

if i do this in command line using bitcoin-cli , then i can get proper output.,

but calling from php json/rpc i am getting warning and no result.

how can i fix this ? thanks for your time.[/code]

EDIT 1 :

on further inspection it seems this is only affected to

getblockhash

as it returns output in int instead of string., and while json doesnt works properly if int starts with 0 ., so it gives warning .,

thats what i think.

EDIT 2 :

if i do this

Code:


[root@localhost ]# curl --user user:password --data-binary '{"id":"curltest", "method": "getblockhash", "params": [502284] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
{"result":"0000000000000000001345b1216c6dfa6e3bdd2774d67c7a85ea6552e2245c08","error":null,"id":"curltest"}

i am getting proper output, so its not issue with bitcoind., but looks like php library.
