How can we retieve values from an API

Question

I have a trouble .From HunterExpress API, I want to fetch freight charge amount for that passing postCode,product dimensions/weight etc I am using the following code to fetch freight charge

$data = array(
    'username' => "xxx",
    'password' => "xxx",
    'customerCode' => "DUMMY",
    'fromLocation' => array( "suburbName"=> "MELBOURNE", "postCode"=> "3000", "state"=> "VIC"),
    'toLocation' =>array( "suburbName"=> "SYDNEY", "postCode"=> "2000", "state"=> "NSW"),
    'goods' =>array( "pieces"=> "2",
    'weight' => "3",
    'width' => "10",
    'height' => "20",
    'depth' => "12",
    'typeCode' => "ENV")
);

$url = "https://api_link";//Api Link
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$result = curl_exec($ch);
echo $result;

But it didn't show any result and no error

It may be the api, it may just be dropping the request because of bad authentication method, look at the return headers. — cujo, Sep 03 '14 at 03:41
What endpoint are you using? Does it go over plain HTTP or HTTPS? What headers are in `$headers`? Are you sure the API expects JSON data? Add some debugging info, like `CURLOPT_HEADER`, `CURLOPT_VERBOSE`, check the return code with `curl_getinfo($ch, CURLINFO_HTTP_CODE)`... — DCoder, Sep 03 '14 at 04:00

Because you didn't initialize your cURL resource. Where is your curl_init() ?

$ch = curl_init();       // without this, there is no cURL to execute

Also fix the syntax error I mentioned in a comment above. Also check for errors

if(curl_exec($ch) === false)
{
    echo 'Curl error: ' . curl_error($ch);
}

when I used the above code it showing "Curl error: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed" – user3931851 Sep 03 '14 at 03:50

Then you also need to disable SSL verification option for your cURL call. You can issue another `setopt` call for that. See here http://stackoverflow.com/questions/6400300/https-and-ssl3-get-server-certificatecertificate-verify-failed-ca-is-ok – Hanky Panky Sep 03 '14 at 03:52

if( !function_exists('curl_version') )
    die("Curl function is disabled");

Check if curl_function is enabled or not
