What potential issues can arise when handling cookies in PHP using fsockopen?
One potential issue when handling cookies in PHP using fsockopen is that the cookies may not be properly set or sent in subsequent requests. To solve this issue, you can manually extract the cookies from the response headers and include them in the subsequent requests.
// Initialize an empty variable to store the cookies
$cookies = '';
// Extract the Set-Cookie headers from the response and concatenate them
while (strpos($response, 'Set-Cookie:') !== false) {
$cookie_start = strpos($response, 'Set-Cookie:') + 12;
$cookie_end = strpos($response, ';', $cookie_start);
$cookies .= substr($response, $cookie_start, $cookie_end - $cookie_start) . '; ';
$response = substr($response, $cookie_end + 1);
}
// Include the cookies in the subsequent requests
$cookie_header = "Cookie: $cookies\r\n";
