PHP Array Cache Adapter
This adapter is a high performance cache for static data (e.g. application configuration) that is optimized and preloaded into OPcache memory storage. It is suited for any data that is mostly read-only after warmup:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
use Symfony\Component\Cache\Adapter\FilesystemAdapter;
use Symfony\Component\Cache\Adapter\PhpArrayAdapter;
// somehow, decide it's time to warm up the cache!
if ($needsWarmup) {
// some static values
$values = [
'stats.products_count' => 4711,
'stats.users_count' => 1356,
];
$cache = new PhpArrayAdapter(
// single file where values are cached
__DIR__ . '/somefile.cache',
// a backup adapter, if you set values after warmup
new FilesystemAdapter()
);
$cache->warmUp($values);
}
// ... then, use the cache!
$cacheItem = $cache->getItem('stats.users_count');
echo $cacheItem->get();Note
This adapter requires turning on the opcache.enable php.ini setting.
