XBMC api get request in php with curl -

i'm trying request xbmc api in php, cant work. have valid url, thats working when simulate request rest client.

http://localhost:8085/jsonrpc?request={"jsonrpc": "2.0", "id": 1, "method": "input.executeaction", "params": {"action":"left"}} 

i parse error xbmc when simulate post:

{ "error": {     "code": -32700,     "message": "parse error." },     "id": null,     "jsonrpc": "2.0" } 

this code have:

<?php     $jsonstring = "{\"jsonrpc\": \"2.0\", \"id\": 1, \"method\": \"input.executeaction\", \"params\": {\"action\":\"left\"}}";     $url = "http://localhost:8085/jsonrpc?request=".$jsonstring;      get($url);      function get($url){         $ch = curl_init();          curl_setopt($ch, curlopt_url, $url);         curl_setopt($ch, curlopt_returntransfer, 1);         curl_setopt($ch, curlopt_connecttimeout , 7);          $result = curl_exec($ch);         print $result;         curl_close($ch);    } 

but wont job, when simulate post request parse error returned. thoughts i'm doing post request, i? if no, problem then?

i ran same problem. need encode url using xbmc (kodi nowadays). in case:

$jsonstring 

should replaced by

urlencode($jsonstring)
