drupal_flush_all_caches()

Flush all cached data on the site.

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.

<?php
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();

  // If invoked from update.php, we must not update the theme information in the
  // database, or this will result in all themes being disabled.
  if (defined('MAINTENANCE_MODE') && MAINTENANCE_MODE == 'update') {
    _system_rebuild_theme_data();
  }
  else {
    system_rebuild_theme_data();
  }

  drupal_theme_rebuild();

  // Don't clear cache_form - in-progress form submissions may break.
  // Ordered so clearing the page cache will always be the last action.

  foreach ($cache_tables as $table) {
