Redis Access

The Redis class allows direct access to an installed Redis server. Most of the more commonly-used Redis methods are available.

Redis::Set($key, $value, $ttl = 0, $overwrite = false)

Set a key into the Redis store.

Redis::Get($key)

Get a value from the Redis store by key.

Redis::Delete($key)

Delete a key from the Redis store immediately.

```php Redis::Flush() ``` Flush the Redis store.

```php Redis::HashGet($key, $field) ``` Returns the value associated with field in the hash stored at key.

```php Redis::HashSet($key, $field, $value) ``` Sets field in the hash stored at key to value. If key does not exist, a new key holding a hash is created. If field already exists in the hash, it is overwritten.

```php Redis::HashGetAll($key) ``` Returns all fields and values of the hash stored at key. In the returned value, every field name is followed by its value, so the length of the reply is twice the size of the hash.

```php Redis::HashKeys($key) ``` Returns all field names in the hash stored at key.

```php Redis::HashLength($key) ``` Returns the number of fields contained in the hash stored at key.

```php Redis::HashMultiSet($key, $values) ``` Multiple sets field in the hash stored at key to value.

```php Redis::ListRange($key, $start, $end) ``` Returns the specified elements of the list stored at key. The offsets start and stop are zero-based indexes, with 0 being the first element of the list (the head of the list), 1 being the next element and so on.

```php Redis::ListTrim($key, $start, $end) ``` Trim an existing list so that it will contain only the specified range of elements specified.

```php Redis::ListIndex($key, $start) ``` Returns the element at index index in the list stored at key.

```php Redis::ListPush($key, $value) ``` Insert all the specified values at the head of the list stored at key. If key does not exist, it is created as empty list before performing the push operations.

```php Redis::ListPop($key) ``` Removes and returns the first element of the list stored at key.

```php Redis::ListLength($key) ``` Returns the length of the list stored at key. If key does not exist, it is interpreted as an empty list and 0 is returned.
