PHP OC_App::isAppVersionCompatible方法代码示例

 /**
  * @brief Installs an app
  * @param $data array with all information
  * @throws \Exception
  * @returns integer
  *
  * This function installs an app. All information needed are passed in the
  * associative array $data.
  * The following keys are required:
  *   - source: string, can be "path" or "http"
  *
  * One of the following keys is required:
  *   - path: path to the file containing the app
  *   - href: link to the downloadable file containing the app
  *
  * The following keys are optional:
  *   - pretend: boolean, if set true the system won't do anything
  *   - noinstall: boolean, if true appinfo/install.php won't be loaded
  *   - inactive: boolean, if set true the appconfig/app.sample.php won't be
  *     renamed
  *
  * This function works as follows
  *   -# fetching the file
  *   -# unzipping it
  *   -# check the code
  *   -# installing the database at appinfo/database.xml
  *   -# including appinfo/install.php
  *   -# setting the installed version
  *
  * It is the task of oc_app_install to create the tables and do whatever is
  * needed to get the app working.
