Answer 1

I would try using CURL:

$urltopost = "http://iphoneimei.info/json/unlock/request";
$datatopost = array (
    "imei" => "012651006507772",
);
$data_string = json_encode($datatopost);
$ch = curl_init ($urltopost);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Accept: application/json',
        'Content-Length: ' . strlen($data_string))
);
$returndata = curl_exec ($ch);

print_r($returndata);

However, the server keep given empty response. I don't know if the server is available for public use like that. Is a authentication token required ?
