Description
int
$lifetime_or_options,?string
$path = null,?string
$domain = null,?bool
$secure = null,?bool
$httponly = null): bool
Alternative signature available as of PHP 7.3.0:
$lifetime_or_options): 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().
