Cross domain for maintaining browser session using CURL - php

Question

I am making a CURL get request via php to another domain to get json value, but as i know curl uses temporary session, but how can i maintain all the browser session in curl request ? here is my code
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://api.json"); //api.json is displaying value from session
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
how can i maintain the browser session ...

Answer 1

You can use the CURLOPT_COOKIEJAR option (see documentation) to save all cookies to a file. You can import this file at a later time using the CURLOPT_COOKIEFILE option, this will send all cookies stored in the specified jar.
Example based on your code for keeping a persistent session between script executions:
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://api.json"); //api.json is displaying value from session
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Set the cookie jar for both importing and exporting
curl_setopt($ch, CURLOPT_COOKIEFILE, "curl-cookie-session.tmp");
curl_setopt($ch, CURLOPT_COOKIEJAR, "curl-cookie-session.tmp");
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$cookie_value = $cookie_name.'='.$_SESSION[$cookie_name];
curl_setopt($ch, CURLOPT_COOKIE, $cookie_value);
$xml_contents = curl_exec ($ch);
curl_close ($ch);
return $xml_contents;
For this you need to store the cookie and in next request attach into the header that works .
