bool

deleteMultiple()

Deletes multiple cache items in a single operation.

public deleteMultiple(mixed $keys) : bool
Parameters
$keys : mixed

A list of string-based keys to be deleted.

Return values
bool

get()

Fetches a value from the cache.

public get(mixed $key[, mixed $default = null ]) : mixed
Parameters
$key : mixed

The unique key of this item in the cache.

$default : mixed = null

Default value to return if the key does not exist.

Return values
mixed

The value of the item from the cache, or $default in case of cache miss.

getMultiple()

Obtains multiple cache items by their unique keys.

public getMultiple(mixed $keys[, mixed $default = null ]) : iteratable<string|int, mixed>
Parameters
$keys : mixed

A list of keys that can obtained in a single operation.

$default : mixed = null

Default value to return for keys that do not exist.

Return values
iteratable<string|int, mixed>

has()

Determines whether an item is present in the cache.

public has(mixed $key) : bool
Parameters
$key : mixed

The cache item key.

public set(mixed $key, mixed $value[, mixed $ttl = null ]) : bool
Parameters
$key : mixed

The key of the item to store.

$value : mixed

The value of the item to store, must be serializable.

bool

setMultiple()

Persists a set of key => value pairs in the cache, with an optional TTL.

public setMultiple(mixed $values[, mixed $ttl = null ]) : bool
Parameters
$values : mixed

A list of key => value pairs for a multiple-set operation.
