When updating a module, it may be necessary to do something that can take a long time. You don't want to time out PHP, do you? Here's how to use Drupal's batch API in hook_update_N():
in mymodule.install
<?php /** * Implements hook_update_N(). * Runs 5 times. */ function mymodule_update_7001(&$sandbox) { $sandbox['total'] = 5; $sandbox['current'] = isset($sandbox['current']) ? $sandbox['current']++ : 1; $sandbox['finished'] = $sandbox['current'] / $sandbox['total']; } ?>
