Deleting from Laravel 4 cache using pattern for key?

Another solution: as long as you are not using file or database cache you can make use of Cache Tags.

Just tag every cache entry with your package name:

Cache::tags('myPackage')->put('config', $config, $minutes);
Cache::tags('myPackage')->put('md5ofafilename', $md5, $minutes);

(You can also use the tags method with remember, forever, and rememberForever)

When it's time to flush the cache of your package's entries just do

Cache::tags('myPackage')->flush();

Note: When you need to access the cache entries you still need to reference the tags. E.g.

$myConfig = Cache::tags('myPackage')->get('config');

That way, another cache entry with key config having a different tag (e.g. hisPackage) will not conflict with yours.

Here is the same solution as in the accepted answer, but rewritten specifically for Redis.

Using KEYS

$redis = Cache::getRedis();
$keys = $redis->keys("*");

foreach ($keys as $key) {
  if (strpos($key, 'mypackage') !== false)
  {
    $redis->del($key);
  }
}

Using SCAN (Redis >= 2.8.0)

$redis = Cache::getRedis();
$cursor = 0;

while($data = $redis->scan($cursor))
{
  $cursor = $data[0];

  foreach($data[1] as $key)
  {
    if (strpos($key, 'mypackage') !== false)
      {
        $redis->del($key);
      }
    }
  }

  if ($cursor == 0) break;
}

Here is a Redis specific example to clear all keys based on a given prefix. This is based on Kazik's answer, with some restructuring and added safety.

Note that RedisStore is under the namespace Illuminate\Cache\RedisStore

$cacheDriver = Cache::driver();
if ($cacheDriver instanceof(RedisStore)) {
    $cursor = 0;
    do {
        $data = $cacheDriver->scan($cursor);
        $cursor = $data[0];
        $cacheEntries = $data[1];

        foreach ($cacheEntries as $key) {
            // This clears based on prefix. Change according to your use case.
            if (starts_with($key, Cache::getPrefix())) {
                $redis->del($key);
            }
        }

    } while ($cursor != 0);
}
