PHP Kohana::cache_life方法代码示例

 /**
  * Initializes the environment:
  *
  * - Disables register_globals and magic_quotes_gpc
  * - Determines the current environment
  * - Set global settings
  * - Sanitizes GET, POST, and COOKIE variables
  * - Converts GET, POST, and COOKIE variables to the global character set
  *
  * The following settings can be set:
  *
  * Type      | Setting    | Description                                    | Default Value
  * ----------|------------|------------------------------------------------|---------------
  * `string`  | base_url   | The base URL for your application.  This should be the *relative* path from your DOCROOT to your `index.php` file, in other words, if Kohana is in a subfolder, set this to the subfolder name, otherwise leave it as the default.  **The leading slash is required**, trailing slash is optional.   | `"/"`
  * `string`  | index_file | The name of the [front controller](http://en.wikipedia.org/wiki/Front_Controller_pattern).  This is used by Kohana to generate relative urls like [HTML::anchor()] and [URL::base()]. This is usually `index.php`.  To [remove index.php from your urls](tutorials/clean-urls), set this to `FALSE`. | `"index.php"`
  * `string`  | charset    | Character set used for all input and output    | `"utf-8"`
  * `string`  | cache_dir  | Kohana's cache directory.  Used by [Kohana::cache] for simple internal caching, like [Fragments](kohana/fragments) and **\[caching database queries](this should link somewhere)**.  This has nothing to do with the [Cache module](cache). | `APPPATH."cache"`
  * `integer` | cache_life | Lifetime, in seconds, of items cached by [Kohana::cache]         | `60`
  * `boolean` | errors     | Should Kohana catch PHP errors and uncaught Exceptions and show the `error_view`. See [Error Handling](kohana/errors) for more info. <br /> <br /> Recommended setting: `TRUE` while developing, `FALSE` on production servers. | `TRUE`
  * `string`  | error_view | The view to use to display errors.  Only used when `errors` is `TRUE`. | `"kohana/error"`
  * `boolean` | profile    | Whether to enable the [Profiler](kohana/profiling). <br /> <br />Recommended setting: `TRUE` while developing, `FALSE` on production servers. | `TRUE`
  * `boolean` | caching    | Cache file locations to speed up [Kohana::find_file].  This has nothing to do with [Kohana::cache], [Fragments](kohana/fragments) or the [Cache module](cache).  <br /> <br />  Recommended setting: `FALSE` while developing, `TRUE` on production servers. | `FALSE`
  *
  * @throws  Kohana_Exception
  * @param   array   Array of settings.  See above.
  * @return  void
  * @uses    Kohana::globals
