Redis's PHP Client

Redis supports a wide variety of clients, including C, Java, PHP, Python, etc., this article mainly introduces the installation and use of PHP client.

Redis's clients actually assume the process of communicating with Redis server over a network protocol, and the process of communication must follow the protocol specification to make the customer's call more consistent with the language-specific usage habits. Existing PHP client: Rediska, Phpredis, Predis, Redisent. These can be justifying, there is a pure PHP implementation, there is a binary version of the implementation of the scheme.

A list of the official PHP clients is as follows:

/*----------------------Predis----------------------------*/

Predis

Predis is a flexible and feature-complete (php>5.3), Redis-enabled PHP client. The current version is 0.6.3, PHP5.2 is not supported by default.

The main features are as follows:

Complete support for Redis from 1.2 to 2.4, and support the currently developing version;

Provides a consistent hashing algorithm for client implementations, supporting customization;

Support for command pipelines in a single or aggregated connection; (command pipelining on aggregated connections)

Ability to connect to Redis via TCP/IP or UNIX domain sockets, supporting persistent connections;

Automatically connect to Redis instances, using lazy mode, and only perform the connection when the first command is issued;

Can flexibly define the client's command set;

Predis Installation

/*-----------------------Phpredis---------------------------*/

Phpredis

This is a binary version of the PHP client, according to the argument, the efficiency is higher than the Predis. This version supports the handler as a session. This extension is a bit more convenient to use without having to load any external files. The disadvantage is that it is difficult to extend, and general PHP programmers cannot extend it. In view of the rapid development of Redis, the lack of extended features still have some impact, need to pay attention to the maintenance process updates.

Installation of integrated XAMPP under MAX (XAMPP Dev environment required)

Sudo/applications/xampp/xamppfiles/bin/phpize

sudo make

sudo make install

Then modify the php.ini and restart the service.

Sample code

Echo ' Phpredis sample:
';

Error_reporting (E_all);

Ini_set (' display_errors ', ' on ');

$redis = new Redis ();

$redis->connect (' 127.0.0.1 ', 6379);

$redis->set (' First_key_phpredis ', ' Hello World ');

);

/*-------------------Rediska-------------------------------*/

Rediska

Rediska is still in the beta phase. His code is hosted on GitHub and can be easily retrieved. The pear version is also available, so it is easy to get and install. You can use the Pear package to install.

This article uses the pear provided by XAMPP under MAC for installation. First add the channel address:

Localhost:bin shiqiang$ sudo./pear channel-discover pear.geometria-lab.net

Password:

Adding Channel "Pear.geometria-lab.net" succeeded

Discovery of channel "Pear.geometria-lab.net" succeeded

Then install the

Localhost:bin shiqiang$ sudo./pear channel-discover pear.geometria-lab.net

Password:

Adding Channel "Pear.geometria-lab.net" succeeded

Discovery of channel "Pear.geometria-lab.net" succeeded

Localhost:bin shiqiang$ sudo./pear Install Geometria-lab/rediska-beta

Unknown Remote channel:pear.zfcampus.org

Did not download optional dependencies:channel://pear.zfcampus.org/zf, use--alldeps to download automatically

Geometria-lab/rediska can optionally use package "CHANNEL://PEAR.ZFCAMPUS.ORG/ZF" (recommended version 1)

Examples of simple use

Error_reporting (E_all);

Ini_set (' display_errors ', ' on ');

$options = Array (

' Namespace ' = ' application_ ',

' Servers ' = Array (

Array (' host ' = ' 127.0.0.1 ', ' port ' = 6379),

Array (' host ' = ' 127.0.0.1 ', ' port ' = 6380)

)

);

Require_once ' rediska.php ';

$rediska = new Rediska ($options);//Create Rediska object, connect to server

$key = new Rediska_key (' First_key ');

$key->setvalue (' First_value ');

$get _value = new Rediska_key (' First_key ');

Print $get _value;//retrieve the stored value

The difference from Memcache

1. The supported data types are diversified. Supports data types such as strings, lists, collections, ordered collections, and hash arrays.

2, you can flexibly specify which server the key is stored on.

Resources:

1, http://rediska.geometria-lab.net/

2. Reids which PHP Module to use

3. PHP Redis

4. Worship Redis
