使用 PHP curl 获取 cookies

Question

I'm trying to get the cookies send by super simple script using the curl . Here are the files:

get_cookie.php:

...
$curl = curl_init("http://.../set_cookie.php");

$data = array('fname'=>"John", 'lname'=>"Brown");
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data)); 
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLINFO_HEADER_OUT, true);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
...
$response = curl_exec($curl);
...
// get cookies
preg_match_all('/^Set-Cookie:\s*([^;]*)/mi', $response, $matches);
$cookies = array();

foreach($matches[1] as $item) {
    parse_str($item, $cookie);
    $cookies = array_merge($cookies, $cookie);
}

echo "cookies recived: <br>";
var_dump($cookies);

set_cookie.php:

...
if (isset($_POST["fname"])) {
    setcookie("usr_name", "user_".$_POST["fname"], time()+60*60);
    ...
}

but on the curl response i get no cookies - the $cookies array is empty (I've checked - the $_POST["fname"] is set - the POST data was sent successfully ). When i call the set_cookie it the standard way - from the browser i get the desired usr_name cookie. What's the problem with curl ?

Answer 1

Have you tried curl_getinfo($curl, CURLINFO_COOKIELIST) instead of parsing manually the response to get cookies?

see https://curl.haxx.se/docs/http-cookies.html
