Api tester

curl from command line
curl -i -X GET "http://localhost/api/index.php?action=list&object=categorias"

i can't make it works inside a PHP with Curl:

$params= array( 'action'=>'list','object'=>'categorias');
$prod = json_decode(Send2Api($url,$params));

function Send2Api($url,$data)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 5);
curl_setopt($ch, CURLOPT_TIMEOUT, 3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
