PHP cURL request is not giving any output

I'm trying to do this command line curl command through PHP cURL, I'm getting the output perfectly in commandline but not the same when I try with PHP.

curl -d "text=terrible" http://text-processing.com/api/sentiment/

Tried to write a PHP cURL but I didn't get any output.

    $data = "text=terrible";
    $ch = curl_init('http://text-processing.com/api/sentiment/');

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

    $response = curl_exec($ch);



  echo "<pre>";
   print_r($response);
    echo "</pre>";

Their API states they require the post to be form encoded data here sentiment api.

Excerpt

To analyze the sentiment of some text, do an HTTP POST to http://text-processing.com/api/sentiment/ with form encoded data containg the text you want to analyze. You’ll get back a JSON object response with 2 attributes:

To do this in PHP with curl, you must pass the header for Content-Type with the value application/x-www-form-urlencoded.

Demonstration

$data = "text=terrible";
$ch = curl_init('http://text-processing.com/api/sentiment/');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

echo "<pre>";
print_r($response);
echo "</pre>";

I think curl is not enable on your end. I tried your code and it is running properly.

Try to enable curl then try it.

  1. Open your php.ini, situated in apache\bin.
  2. Uncomment ;extension=php_curl.dll.
  3. Restart Apache.

Hope this will help
