PHP添加Redis模块及连接
上几篇文章介绍了Redis的安装及使用,下面将介绍php如何添加Redis扩展!
php手册并没有提供Redis的类和方法,也没有提供相关的扩展模块,但我们可以在Redis的官网下载PHP的扩展,里面的扩展比较多,仅以phpredis为例。
- phpredis下载
- 点击"Repository"进入Redis的学习库,里面有Redis扩展的代码文件和相关的介绍以及类和方法
- 点击"releases"进入phpredis的源文件
- 下载最新版的phpredis源文件,选择"tar.gz"下载
- 点击"Repository"进入Redis的学习库,里面有Redis扩展的代码文件和相关的介绍以及类和方法
- phpredis配置
- 解压phpredis文件

- 安装配置phpredis
- 在phpredis目录下运行phpize5命令,生成configure文件
phpize5
- 安装配置igbinary
wget http:<span style="color: #008000;">//</span><span style="color: #008000;">pecl.php.net/get/igbinary-1.2.1.tgz</span>./<span style="color: #000000;">configuremakesudo make install</span>
- 安装配置phpredis
./configure --enable-redis-<span style="color: #000000;">igbinarymake <br></span>sudo make install
- 修改php.ini,添加(要按顺序,先添加igbinary.so,再添加redis.so)
extension=igbinary.<span style="color: #000000;">soextension</span>=redis.so
- 查看phpredis
- 使用phpinfo()查看
- php连接redis数据库
- 开启数据库服务
- 新建一个redis.php文件,并键入以下代码进行连接

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
