Empties cache tables, rebuilds the menu cache and theme registries, and invokes a hook so that other modules' cache data can be cleared as well.

Common functions that many Drupal modules will need to reference.

Code

function drupal_flush_all_caches() {
  // Change query-strings on css/js files to enforce reload for all users.
  _drupal_flush_css_js();

  registry_rebuild();
  drupal_clear_css_cache();
  drupal_clear_js_cache();

  // Rebuild the theme data. Note that the module data is rebuilt above, as
  // part of registry_rebuild().
  system_rebuild_theme_data();
  drupal_theme_rebuild();

  entity_info_cache_clear();
  node_types_rebuild();
  // node_menu() defines menu items based on node types so it needs to come
  // after node types are rebuilt.
  menu_rebuild();

  // Synchronize to catch any actions that were added or removed.
  actions_synchronize();

  // Don't clear cache_form - in-progress form submissions may break.
  // Ordered so clearing the page cache will always be the last action.
  $core = array('cache', 'cache_path', 'cache_filter', 'cache_bootstrap', 'cache_page');
  $cache_tables = array_merge(module_invoke_all('flush_caches'), $core);
  foreach ($cache_tables as $table) {
    cache_clear_all('*', $table, TRUE);
  }

  // Rebuild the bootstrap module list. We do this here so that developers
  // can get new hook_boot() implementations registered without having to
  // write a hook_update_N() function.
  _system_update_bootstrap_status();
