FileCache

Inheritance diagram for FileCache:

Description

An optional bare bones PSR-16 "compliant" file-based cache for SimpleCachePool.

Requires psr/simple-cache (any version).

This is not safe for concurrency.

Don't use this if you have a better cache.

Parameters

string

$dir

Methods

clear()

bool clear

(

)

Does nothing.

Returns

bool false

delete()

bool delete

(

$key

)

CacheInterface:1|2 compatible params.

Parameters

string

$key

Returns

bool

deleteMultiple()

bool deleteMultiple

(

$keys

)

CacheInterface:1|2 compatible params.

Parameters

iterable

$keys

Returns

bool

get()

string object mixed get	(		$key,
			$default = null
	)

CacheInterface:1|2 compatible params.

Parameters

string	$key
mixed	$default

Returns

string|object|mixed $default is the only mixed type returned

getMultiple()

array getMultiple	(		$keys,
			$default = null
	)

CacheInterface:1|2 compatible params.

Parameters

iterable	$keys
mixed	$default

Returns

array

has()

bool has

(

$key

)

CacheInterface:1|2 compatible params.

This only checks for file existence, regardless of expiration. This is fine, since by principle, cache polling does not guarantee a subsequent hit.

Parameters

string

$key

Returns

bool

			$ttl = null
	)

CacheInterface:1|2 compatible params.

Parameters

string	$key
string | object	$value
null | int | DateInterval	$ttl	NULL is the same as 0 seconds.

Returns

bool

setLog()

$this setLog

(

?LoggerInterface

$log

)

Parameters

null | LoggerInterface
