//Ignore SSL certificate verification
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
//get response
$output = curl_exec($ch);
//Print error if any
if(curl_errno($ch))
{
    echo curl_error($ch)."-curl_error<br/>";
    $chcode =curl_errno($ch); 
    echo $chcode;
    echo '<br/>error:' . curl_strerror($chcode)."<br/>";
}
curl_close($ch);
echo $output;

Curl_errorno() is not executing, even if i print them without if condition they give no result.

Try this

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_ENCODING, '');
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));

$server_output = curl_exec($ch);
curl_close($ch);

print_r($server_output);
