GET request via CURL in PHP

Question

I have CURL script as below:

$url= 'https://www.test.com/test.php';
$msg=?p1={1250.feed}&p2={jt2221}&p3={1330}&p4={1234567890}&p5={2016-02-04 20:05:34}&p6={New York}; 

$url .= $msg;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
}
$http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

var_dump($http_status);
var_dump($result);

the full string url and message , when I copy/past on Chrome web browser the remote PHP file receives well. When same url+message sent by PHP script not works. I guess the problem is first the remote domain is HTTPS , second seems curly brackets and space disturbs the CURL request.I tried urlencode($msg) function then got Error 404 . On success sent message , remote PHP returns {"Code":null,"Msg":"."} as ACK

If you are using urlencode , you'll just want to encode the values, not the whole query string. An efficient way to do this (and keep your query data in neat arrays) is with http_build_query :

$url= 'https://www.test.com/test.php?';

$data = array('p1' => '{1250.feed}',
              'p2' => '{jt2221}',
              'p3' => '{1330}',
              'p4' => '{1234567890}',
              'p5' => '{2016-02-04 20:05:34}',
              'p6' => '{New York}',);

$msg = http_build_query($data);

$url .= $msg;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
curl_close($ch);
if (curl_errno($ch)) {
    echo 'Error: ' . curl_error($ch);
}
$http_status = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

var_dump($http_status);
var_dump($result);
