PHP setcookie() function is used to set cookie with HTTP response.
Syntax:
setcookie(name, value, expire, path, domain, secure, httponly);
- name: The name of the cookie.
- value: The value of the cookie.
- expire: The expiration time as a Unix timestamp. If set to 0, the cookie will expire at the end of the session.
- path: The path on the server in which the cookie will be available. Default is the current directory.
- domain: The domain that the cookie is available to. Default is the domain of the current script.
- secure: Indicates if the cookie should only be transmitted over secure HTTPS connections. Default is false.
- httponly: When set to true, the cookie will be accessible only through the HTTP protocol and not via JavaScript. Default is false.
Example:
// Setting a cookie with a 30-day expiration
setcookie("user", "John Doe", time() + (86400 * 30), "/");
// Setting a cookie with HTTP Only flag
setcookie("session_id", "123456", time() + 3600, "/", "", true, true);
