Làm cách nào để thêm Redis trong PHP?

Tiện ích mở rộng phpredis cung cấp API để giao tiếp với kho lưu trữ khóa-giá trị Redis. Nó được phát hành theo Giấy phép PHP, phiên bản 3. 01. Mã này đã được Owlient phát triển và duy trì từ tháng 11 năm 2009 đến tháng 3 năm 2011

Tài liệu API

Đây là một công việc đang được tiến hành, nhưng cuối cùng sẽ thay thế MỘT README ĐỂ QUY ĐỊNH TẤT CẢ các tài liệu của chúng tôi

Hỗ trợ dự án

PhpRedis sẽ luôn là phần mềm nguồn mở và miễn phí, nhưng nếu bạn hoặc công ty của bạn thấy nó hữu ích, vui lòng cân nhắc hỗ trợ dự án. Việc phát triển một thư viện lớn, phức tạp và hiệu quả như PhpRedis cần rất nhiều thời gian và công sức, và sự hỗ trợ sẽ được đánh giá cao. ❤️

Cách tốt nhất để hỗ trợ dự án là thông qua các nhà tài trợ GitHub. Nhiều bậc phần thưởng cấp quyền truy cập vào kênh chùng của chúng tôi, nơi tôi và Pavlo thường xuyên có mặt để trả lời các câu hỏi. Ngoài ra, điều này sẽ cho phép bạn cung cấp phản hồi về các bản sửa lỗi và tính năng mới cần ưu tiên

Installing/Configuring

Installation

For everything you should need to install PhpRedis on your system, see the INSTALL. md page

PHP Session handler

phpredis can be used to store PHP sessions. To do this, configure 

# Run tests for Redis class [note this is the default]

16 scheme if you want to use the parameters. The following parameters are available

  • weight [integer]. the weight of a host is used in comparison with the others in order to customize the session distribution on several hosts. If host A has twice the weight of host B, it will get twice the amount of sessions. In the example, host1 stores 20% of all the sessions [1/[1+2+2]] while host2 and host3 each store 40% [2/[1+2+2]]. The target host is determined once and for all at the start of the session, and doesn't change. The default weight is 1
  • timeout [float]. the connection timeout to a redis host, expressed in seconds. If the host is unreachable in that amount of time, the session storage will be unavailable for the client. The default timeout is very high [86400 seconds]
  • persistent [integer, should be 1 or 0]. defines if a persistent connection should be used
  • prefix [string, defaults to "PHPREDIS_SESSION. "]. used as a prefix to the Redis key in which the session is stored. The key is composed of the prefix followed by the session ID
  • auth [string, or an array with one or two elements]. used to authenticate with the server prior to sending commands
  • database [integer]. selects a different database

Sessions have a lifetime expressed in seconds and stored in the INI variable "session. gc_maxlifetime". Bạn có thể thay đổi nó bằng

khóa phiên

Ủng hộ. Tính năng khóa hiện chỉ được hỗ trợ cho thiết lập Redis với phiên bản chính duy nhất [e. g. môi trường Sentinel chính/nô lệ cổ điển]. Vì vậy, khóa có thể không hoạt động bình thường trong môi trường RedisArray hoặc RedisCluster

Các biến INI sau có thể được sử dụng để định cấu hình khóa phiên

; Should the locking be enabled? Defaults to: 0.
redis.session.locking_enabled = 1
; How long should the lock live [in seconds]? Defaults to: value of max_execution_time.
redis.session.lock_expire = 60
; How long to wait between attempts to acquire lock, in microseconds [µs]?. Defaults to: 20000
redis.session.lock_wait_time = 50000
; Maximum number of times to retry [-1 means infinite]. Defaults to: 100
redis.session.lock_retries = 2000

Running the unit tests

phpredis uses a small custom unit test suite for testing functionality of the various classes. Để chạy thử nghiệm, chỉ cần làm như sau

# Run tests for Redis class [note this is the default]
php tests/TestRedis.php --class Redis

# Run tests for RedisArray class
tests/mkring.sh start
php tests/TestRedis.php --class RedisArray
tests/mkring.sh stop

# Run tests for the RedisCluster class
tests/make-cluster.sh start
php tests/TestRedis.php --class RedisCluster
tests/make-cluster.sh stop

# Run tests for RedisSentinel class
php tests/TestRedis.php --class RedisSentinel

Note that it is possible to run only tests which match a substring of the test itself by passing the additional argument '--test ' when invoking

# Just run the 'echo' test
php tests/TestRedis.php --class Redis --test echo

Classes and methods

Usage

Class Redis

Description. Creates a Redis client

Example

$redis = new Redis[];

Starting from version 6. 0. 0 it's possible to specify configuration options. This allows to connect lazily to the server without explicitly invoking 

# Run tests for Redis class [note this is the default]
php tests/TestRedis.php --class Redis

# Run tests for RedisArray class
tests/mkring.sh start
php tests/TestRedis.php --class RedisArray
tests/mkring.sh stop

# Run tests for the RedisCluster class
tests/make-cluster.sh start
php tests/TestRedis.php --class RedisCluster
tests/make-cluster.sh stop

# Run tests for RedisSentinel class
php tests/TestRedis.php --class RedisSentinel
22 command

Example

$redis = new Redis[[
    'host' => '127.0.0.1',
    'port' => 6379,
    'connectTimeout' => 2.5,
    'auth' => ['phpredis', 'phpredis'],
    'ssl' => ['verify_peer' => false],
    'backoff' => [
        'algorithm' => Redis::BACKOFF_ALGORITHM_DECORRELATED_JITTER,
        'base' => 500,
        'cap' => 750,
    ],
]];

Parameters

host. chuỗi. can be a host, or the path to a unix domain socket
port. int [default is 6379, should be -1 for unix domain socket]
connectTimeout. float, value in seconds [default is 0 meaning unlimited]
retryInterval. int, value in milliseconds [optional]
readTimeout. float, value in seconds [default is 0 meaning unlimited]
persistent. mixed, if value is string then it used as persistend id, else value casts to boolean
auth. mixed, authentication information
ssl. array, SSL context options

Class RedisException

phpredis throws a object if it can't reach the Redis server. That can happen in case of connectivity issues, if the Redis service is down, or if the redis host is overloaded. In any other problematic case that does not involve an unreachable server [such as a key not existing, an invalid command, etc], phpredis will return

Kết nối sẽ không bị đóng khi kết thúc yêu cầu cho đến khi quá trình php kết thúc. So be prepared for too many open FD's errors [specially on redis server side] when using persistent connections on many servers connecting to one redis server

Also more than one persistent connection can be made identified by either host + port + timeout or host + persistent_id or unix socket + timeout

Starting from version 4. 2. 1, it became possible to use connection pooling by setting INI variable

Description. Return members of a set with geospatial information that are within the radius specified by the caller

Options Array

The georadius command can be called with various options that control how Redis returns results. The following table describes the options phpredis supports. All options are case insensitive

KeyValueDescriptionCOUNTinteger > 0Limit how many results are returnedWITHCOORDReturn longitude and latitude of matching membersWITHDISTReturn the distance from the centerWITHHASHReturn the raw geohash-encoded scoreASCSort results in ascending orderDESCSort results in descending orderSTOREkeyStore results in keySTOREDISTkeyStore the results as distances in key

Note. It doesn't make sense to pass both 

$redis = new Redis[];
32 and 
$redis = new Redis[];
33 options but if both are passed the last one passed will be used
Note. When using 
$redis = new Redis[];
34 in Redis Cluster, the store key must has to the same slot as the query key or you will get a 
$redis = new Redis[];
35 error

Return value

Mixed. When no 

$redis = new Redis[];
36 option is passed, this function returns an array of results. If it is passed this function returns the number of stored entries

This can be useful if phpredis is serializing values, and you return something from redis in a LUA script that is serialized

Parameters

chuỗi giá trị. The value to be unserialized

ví dụ

# Run tests for Redis class [note this is the default]
php tests/TestRedis.php --class Redis

# Run tests for RedisArray class
