Drupal Gotchya: Cache_get() Returns Expired Items
29 July 2009 - 6:21pm — Bevancache_get() returns $cache objects even if the cached item is stale (expired). The cached data will not be rebuilt every hour in the following example:
<?php
/**
* Builds complicated data for the monkey grip.
*/
function custom_monkey_grip_data() {
// Return the cached data
$cache = cache_get('custom:monkey_grip');
if (!$cache) {
// Some expensive processing to build the data.
$data = complicated_recursion_and_loops_on_lots_of_data();
// Cache the data and rebuild it every hour
$expire = time() + (60 * 60);
cache_set('custom:monkey_grip', $data, 'cache', $expire);
}
else {
$data = $cache->data;
}
return $data;
}
