(PHP 4, PHP 5, PHP 7, PHP 8)
session_set_cookie_params — Set the session cookie parameters
$lifetime_or_options,$path = null,$domain = null,$secure = null,$httponly = nullAlternative 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().
lifetime_or_optionsWhen using the first signature, lifetime of the session cookie, defined in seconds.
When using the second signature,
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.
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.
Returns true on success or false on failure.
