Methods

__construct()

__construct(array  $params = array())

Constructor.

Parameters

array $params

Configuration parameters:

__set()

__set(  $name,   $val)

Parameters

$name
$val

__get()

__get(  $name)

Parameters

$name

delete()

delete(mixed  $keys) : boolean

Delete a key(s).

Parameters

mixed $keys

The key or an array of keys to delete.

Returns

boolean —

True on success.

exists()

exists(mixed  $keys) : mixed

Do the keys exists?

Parameters

mixed $keys

The key or an array of keys.

Returns

mixed —

A boolean/array of booleans indicating existence (return type is the type of $keys).

get()

get(mixed  $keys) : mixed

Get data associated with a key(s).

Parameters

mixed $keys

The key or an array of keys.

Returns

mixed —

The string/array on success (return type is the type of $keys); false value(s) on failure.

set()

set(string  $key, string  $val, array  $opts = array()) : boolean

Set the value of a key.

Parameters

string $key

The key.
string $val

The string to store.
array $opts

Additional options:

  - expire: (integer) Expiration time in seconds.
            DEFAULT: Doesn't expire.
  - replace: (boolean) Replace the value of key. If key doesn't exist,
             returns false.
             DEFAULT: false

Returns

boolean —

True on success, false on error.

clear()

clear()
