session_cache_expire — Get and/or set current cache expire

### Description

session_cache_expire(?int `$value` = `null`): int|false

session_cache_expire() returns the current setting of `session.cache_expire`.

The cache expire is reset to the default value of 180 stored in session.cache_expire at request startup time. Thus, you need to call session_cache_expire() for every request (and before session_start() is called).

### Parameters

`value`

  If `value` is given and not `null`, the current cache expire is replaced with `value`.

  > Note: Setting `value` is of value only, if `session.cache_limiter` is set to a value different from `nocache`.

### Return Values

Returns the current setting of `session.cache_expire`. The value returned should be read in minutes, defaults to 180. On failure to change the value, `false` is returned.

### Changelog

Version | Description
--- | ---
8.0.0 | `value` is nullable now.

### Examples
