PHP PageManager::resolvePageByPath方法代码示例

 /**
  * This function attempts to resolve the given page in to it's Symphony page. If no
  * page is given, it is assumed the 'index' is being requested. Before a page row is
  * returned, it is checked to see that if it has the 'admin' type, that the requesting
  * user is authenticated as a Symphony author. If they are not, the Symphony 403
  * page is returned (whether that be set as a user defined page using the page type
  * of 403, or just returning the Default Symphony 403 error page). Any URL parameters
  * set on the page are added to the `$env` variable before the function returns an
  * associative array of page details such as Title, Content Type etc.
  *
  * @uses FrontendPrePageResolve
  * @see __isSchemaValid()
  * @param string $page
  * The URL of the current page that is being Rendered as returned by `getCurrentPage()`.
  * If no URL is provided, Symphony assumes the Page with the type 'index' is being
  * requested.
  * @return array
  *  An associative array of page details
