The above code is not perfect. We should store the cookie in the cache and should not persist it, and such persistence can only be accessed by a single user.

So, actually we just need to set

CURLOPT_COOKIESESSION

Just do the following

$data='username=demo_demo@126.com&password=123456qwe&remember=1';
$curlobj = curl_init(); // Initialization
curl_setopt($curlobj, CURLOPT_URL , "http://www.imooc.com/user/login"); // Set the URL to access the web page
curl_setopt($curlobj, CURLOPT_RETURNTRANSFER, true); // Do not print it out directly after execution

// Cookie related Settings, this part of the setting needs to be set before all sessions start
date_default_timezone_set('PRC'); // When using cookies, the time zone must be set first
curl_setopt($curlobj, CURLOPT_COOKIESESSION, TRUE);
curl_setopt($curlobj, CURLOPT_HEADER, 0 );
curl_setopt($curlobj, CURLOPT_COOKIE,session_name().'='.session_id());
// Comment out this line, because this setting must turn off safe mode and open_basedir, which is not good for server security
//curl_setopt ($curlobj, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($curlobj, CURLOPT_POST, 1);
curl_setopt($curlobj, CURLOPT_POSTFIELDS, $data);
curl_setopt($curlobj, CURLOPT_HTTPHEADER, array("application/x-www - form-urlencoded; charset=utf-8",
 "Content-length: ".strlen($data)

curl_exec($curlobj); // Execute
curl_setopt($curlobj, CURLOPT_URL, "http:/ /www.imooc.com/space/index");
curl_setopt($curlobj, CURLOPT_POST, 0);
curl_setopt($curlobj, CURLOPT_HTTPHEADER, array("Content-type: text/xml"
 ));
$output =curl_redir_exec($curlobj); // Execute
curl_close($curlobj); // Close cURL
echo $output;
