PHP OC_App::getInstallPath方法代码示例

 /**
  * Removes an app

  *
  * This function removes an app. $options is an associative array. The
  * following keys are optional:ja
  *   - keeppreferences: boolean, if true the user preferences won't be deleted
  *   - keepappconfig: boolean, if true the config will be kept
  *   - keeptables: boolean, if true the database will be kept
  *   - keepfiles: boolean, if true the user files will be kept
  *
  * This function works as follows
  *   -# including appinfo/remove.php
  *   -# removing the files
  *
  * The function will not delete preferences, tables and the configuration,
  * this has to be done by the function oc_app_uninstall().
