Error on cURL with POST data

Question

I want to extract data from this URL with Php Curl:

https://www.traveloka.com/en/flight/fullsearch?ap=JKTA.DPS&dt=14-10-2017.NA&ps=1.0.0&sc=ECONOMY

Answer 1

As per the URL you have given using the below code, you would get nothing rather the redirection link:

Replace with the link and parameters with the correct api:

General format of using CURL is given here:

            $ch = curl_init();

           $params = urldecode('{"ap":"' . 'JKTA.DPS' . '","dt":"' . '14-10-2017.NA' . '","ps":"' . '1.0.0'. '","sc":"' . 'ECONOMY'. '"}');



            $url = 'https://www.traveloka.com/en/flight/fullsearch?JsonData=' . $params;
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            // curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0");

            curl_setopt($ch, CURLOPT_HEADER, 0);

            // Should cURL return or print out the data? (true = return, false = print)
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

            // Timeout in seconds
            curl_setopt($ch, CURLOPT_TIMEOUT, 10);

            // Download the given URL, and return output
            $output = curl_exec($ch);

            // Close the cURL resource, and free system resources
            curl_close($ch);

            if (!empty($output)) {
                $x = json_decode($output, true);
                        var_dump($x);   
                   }else{
                      return FALSE;
                   }

What you want to do is called Web scrapping, there are plenty of tools that you can use to do that. For now, go for: https://github.com/FriendsOfPHP/Goutte or https://github.com/duzun/hQuery.php.
