How is Redis used and encapsulated in the ThinkPHP5 framework?

The followingthinkphp frameworkThe tutorial column will introduce to you how to use and encapsulate Redis in ThinkPHP5.0. I hope it will be helpful to friends in need!

Redis is a commonly used non-relational database, mainly used for data caching. The data is saved in the form of key-value, and the key values ​​map to each other. Its data storage is different from MySQL, and its data is stored in memory. , so data reading is relatively fast, which is very good for high concurrency.

ThinkPhP5.0 comes with a Redis extension. Before using it, download php_redis.dll at http://windows. php.net/downloads/pecl/releases/redis/2.2.7/ ;Choose the corresponding version according to your windows operating system. My system is 64-bit and I installed VC2012, so I downloaded php_redis-2.2.7-5.6- ts-vc11-x64.zip

After downloading the compressed package, unzip the php_redis.dll inside to D:\wamp\bin\php\php5.6.25\ext (choose according to the disk where your wamp is located) ), then add extension=php_redis.dll in php.ini and restart apache;

The following is the code I tested myself. It can be used. There are not many packages. You can customize it according to your own needs. Hands-on encapsulation

extend is the extended class library directory of thinkPHP5.0. You can define it yourself

namespace My;　　//目录我放在thinkphp5.0/extend/My  

class RedisPackage

    protected static $handler = null;
    protected $options = [
        'host' => '127.0.0.1',
        'port' => 6379,
        'password' => '',
        'select' => 0,
        'timeout' => 0,　　　　//关闭时间 0:代表不关闭
        'expire' => 0,
        'persistent' => false,
        'prefix' => '',
    ];

    public function __construct($options = [])
    {
        if (!extension_loaded('redis')) {   //判断是否有扩展(如果你的apache没reids扩展就会抛出这个异常)
            throw new \BadFunctionCallException('not support: redis');      
        }
        if (!empty($options)) {
            $this->options = array_merge($this->options, $options);
        }
        $func = $this->options['persistent'] ? 'pconnect' : 'connect';     //判断是否长连接
        self::$handler = new \Redis;
        self::$handler->$func($this->options['host'], $this->options['port'], $this->options['timeout']);

        if ('' != $this->options['password']) {
            self::$handler->auth($this->options['password']);
        }

        if (0 != $this->options['select']) {
            self::$handler->select($this->options['select']);
        }
    }
