   ) : boolSet cookie parameters defined in the php.ini file. The effect of this function only lasts for the duration of the script. Thus, you need to call session_set_cookie_params() for every request and before session_start() is called.
This function updates the runtime ini values of the corresponding PHP ini configuration keys which can be retrieved with the ini_get().
lifetimeLifetime of the session cookie, defined in seconds.
pathPath on the domain where the cookie will work. Use a single slash ('/') for all paths on the domain.
domainCookie domain, for example 'www.php.net'. To make cookies visible on all subdomains then the domain must be prefixed with a dot like '.php.net'.
secure
       If TRUE cookie will only be sent over
       secure connections.
      
httponly
       If set to TRUE then PHP will attempt to send the
       httponly
       flag when setting the session cookie.
      
options
       An associative array which may have any of the keys
       lifetime, path, domain,
       secure, httponly and samesite.
       The values have the same meaning as described for the parameters with the
       same name. The value of the samesite element should be
       either Lax or Strict.
       If any of the allowed options are not given, their default values are the
       same as the default values of the explicit parameters. If the
       samesite element is omitted, no SameSite cookie
       attribute is set.
      
   Returns TRUE on success or FALSE on failure.
