Redis PHP client

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

The Redis client is actually responsible for the communication process with the Redis Server through the network protocol. the communication process must follow the protocol specifications, so that the customer's call is more in line with the usage habits of specific languages. Existing PHP clients: rediska, phpredis, Predis, and Redisent. Among these benefits, there are pure PHP implementation solutions and binary implementation solutions.

The official PHP client list is as follows:

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

Predis

Predis is a PHP client that supports Redis with flexibility and complete features (PHP> 5.3. The current version is 0.6.3. PHP5.2 is not supported by default.

The main features are as follows:

Fully supports Redis from 1.2 to 2.4, and supports the currently developing version;

Provides consistent hash algorithms implemented by clients and supports customization;

Supports Command pipelines in a single or aggregate connection. (Command pipelining on single and aggregated connections)

You can use TCP/IP or Unix domain sockets to connect to redis and support persistent connections;

Automatically connects to the apsaradb for Redis instance. the connection is executed only when the first command is sent;

A set of client commands can be flexibly defined;

Predis installation

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

Phpredis

This is a binary PHP client, which is more efficient than Predis. This version supports Session Handler. This extension is easy to use without loading any external files. The disadvantage is that it is difficult to expand. generally, PHP programmers cannot extend it. Considering that Redis is developing rapidly and the lack of extended features still has some impact, you need to upgrade and update during the maintenance process.

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

Rediska

Rediska is currently in beta stage. His code is hosted on github for easy access. The PEAR version is also provided, so it is very convenient to obtain and install it. You can use the PEAR package for installation.

This article uses the PEAR provided by XAMPP on 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

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)

Simple example

Error_reporting (E_ALL );

Ini_set ('display _ errors ', 'on ');

$ Options = array (

'Namespace' => 'application _',

'Servers' => array (

Array ('host' => '127. 0.0.1 ', 'port' => 127 ),

Array ('host' => '127. 0.0.1 ', 'port' => 127)

)

);

Require_once 'rediska. php ';

$ Rediska = new Rediska ($ options); // Create a Rediska object and connect to the server

$ Key = new Rediska_Key ('First _ key ');

$ Key-> setValue ('First _ value ');

$ Get_value = new Rediska_Key ('First _ key ');

Print $ get_value; // retrieves the stored value

Differences from Memcache

1. diversified data types are supported. Data types such as string, list, set, ordered set, and Hash array are supported.

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