- Checks whether the driver is available and a provider can be made.
- parseDsn() : ValkeyProviderInfo
- Constructs a cache info instance from a dsn.
Methods
createProvider()
Creates a Valkey cache provider.
public
createProvider(ValkeyProviderInfo $providerInfo) : ValkeyProvider
Parameters
- $providerInfo : ValkeyProviderInfo
-
Valkey provider info.
Return values
ValkeyProvider —Valkey provider instance.
isAvailable()
Checks whether the driver is available and a provider can be made.
public
isAvailable() : bool
Return values
bool —If true a provider can be made, if false a required extension is missing.
parseDsn()
Constructs a cache info instance from a dsn.
public
parseDsn(string|array<string|int, mixed> $dsn) : ValkeyProviderInfo
The Valkey backend supports setting a username and password in the URL.
//username:password@ is treated as a username and password.
//username@ is treated as just a password despite what is normally expected of a URL. Older versions of Redis did not have the concept of usernames.
In order to still use a username but no password for some reason you can specify //username:@, just inserting a colon without anything after it.
The host part of the URL can be any DNS name, or special value :unix:, documented further down.
The path part of the URL is used as a key prefix. Any prefix slashes (/) are trimmed and others are converted to a colon (:).
Meaning /prefix/test/ is converted to prefix:test:.
In order to use a Unix socket path, set the host part to :unix: and specify socket=/path/to/socket.sock in the query.
Other query fields include:
-
db=<number>: Allows you to select a different database. -
persist: Uses a persistent connection.
Parameters
- $dsn : string|array<string|int, mixed>
-
DSN with provider information.
Return values
ValkeyProviderInfo —Valkey provider info instance.
