Function:Return the expiration time of the current cache
Syntax: int session_cache_expire ([ string $new_cache_expire ] )
Parameters:
| Parameter | Description |
| new_cache_expire | If given new_cache_expire, use the value of new_cache_expire to set the current cache expiration time. |
Description: session_cache_expire() returns the setting value of session.cache_expire. When the request starts, the cache expiration time will be reset to 180 and stored in the session.cache_expire configuration item. Therefore, for each request, session_cache_expire() needs to be called before the session_start() function is called to set the cache expiration time.
