PHP Kohana::cache_lifetime方法代码示例

 /**
  * Sets up the PHP environment. Adds error/exception handling, output
  * buffering, and adds an auto-loading method for loading classes.
  *
  * This method is run immediately when this file is loaded, and is
  * benchmarked as environment_setup.
  *
  * For security, this function also destroys the $_REQUEST global variable.
  * Using the proper global (GET, POST, COOKIE, etc) is inherently more secure.
  * The recommended way to fetch a global variable is using the Input library.
  * @see http://www.php.net/globals
