cURL - sending GET request using PHP

Question

I can't understand where i am doing wrong.

below is my code:

$message = "testing from the application.";
$mobile_number = ""; //hidden for security
$sender = ""; //hidden for security    
$ch = curl_init(""); //hidden for security, http://ip
curl_setopt($ch, CURLOPT_URL, "api.php?username=&password=&number=$mobile_number&sender=$sender&type=0&message=$message");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
echo $output = curl_exec($ch);
echo curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

curl_getinfo return 0, and $output did't return anything, but the Document says if the request successful then the $output is 1101.

I tested it in the postman, the result is ok.

`curl_setopt($ch, CURLOPT_URL, "api.php?username=&password=&number=$mobile_number&sender=$sender&type=0&message=$message");` here you are passing the values are not? Also what `var_dump(echo $output);` and `var_dump(curl_getinfo($ch, CURLINFO_HTTP_CODE));` says? — Alive to die - Anant, Apr 02 '16 at 17:26
hidden for security, but if i give some values there its work in postman. i already says what other two return. — Murad Hasan, Apr 02 '16 at 17:30
Also you need to specify the POST true,AFAIK curl defaults to GET http://stackoverflow.com/questions/13921867/curl-not-working-with-post-data — Mihai, Apr 02 '16 at 17:34
@Mihai i have a GET Request, and after i encode the url, its remain same. — Murad Hasan, Apr 02 '16 at 17:35
Test it directly,use something like httpfox in firefox to see the headers and go to that url in the browser — Mihai, Apr 02 '16 at 17:38
I tested the url in gooogle postman, its work fine there, but i don't know why the same url not working with PHP. — Murad Hasan, Apr 02 '16 at 17:39
@Mihai, I got the problem, The message contain the spaces, so the url not working. how to encode the message so the space not a problem? — Murad Hasan, Apr 02 '16 at 17:44

Based on your final comment, since the problem was due to the URL parameters not being url encoded, the simplest way to do so I think is like this:

$params = array(
    'message'  => "testing from the application.",
    'number'   => "", //hidden
    'sender'   => "", //hidden
    'username' => $username,
    'password' => $password,
    'type'     => 0,
);

$url = 'api.php?'. http_build_query($params);

curl_setopt($ch, CURLOPT_URL, $url);

See http_build_query() for more information. It will safely encode the array into a string suitable for URL encoded HTTP POST requests, or for query string parameters.

When a cURL request fails, seeing everything returned by curl_getinfo() is helpful too.

In this case I would have thought the HTTP code would have been 400, for bad request. Also you call do echo curl_error($ch); for a human-readable error message.

i use same as you say but the message is `HTTP/1.1 400 Bad Request Date: Fri, 08 Apr 2016 05:25:15 GMT Accept-Ranges: bytes Server: LiteSpeed Connection: close ` — Murad Hasan, Apr 08 '16 at 05:26
yes, it works, you miss to remove the space here after `?' . `in `'api.php?' . http_build_query($params);` — Murad Hasan, Apr 08 '16 at 05:37
