安装
要在PHP程序中使用Redis,首先需要确保 Redis 的PHP驱动程序和 PHP 安装设置在机器上。可以查看 PHP教程 教你如何在机器上安装PHP。现在,让我们来看看一下如何设置 Redis 的PHP驱动程序。
需要从 github 上资料库: https://github.com/nicolasff/phpredis 下载 phpredis。下载完成以后,将文件解压缩到 phpredis 目录。在 Ubuntu 上安装这个扩展,可使用如下图所示的命令来安装。
cd phpredis
sudo phpize
sudo ./configure
sudo make
sudo make install
现在,复制和粘贴“modules”文件夹的内容复制到PHP扩展目录中,并在 php.ini 中添加以下几行。
extension = redis.so
现在 Redis 和 PHP 安装完成
连接到Redis服务器
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
//check whether server is running or not
echo "Server is running: " . $redis->ping();
?>
当执行程序时,会产生下面的结果:
Connection to server sucessfully
Server is running: PONG
Redis的PHP字符串实例
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
//set the data in redis string
$redis->set("tutorial-name", "Redis tutorial");
// Get the stored data and print it
echo "Stored string in redis:: " . $redis.get("tutorial-name");
?>
当执行程序时,会产生下面的结果:
Connection to server sucessfully
Stored string in redis:: Redis tutorial
Redis的PHP列表示例
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
//store data in redis list
$redis->lpush("tutorial-list", "Redis");
$redis->lpush("tutorial-list", "Mongodb");
$redis->lpush("tutorial-list", "Mysql");
// Get the stored data and print it
$arList = $redis->lrange("tutorial-list", 0 ,5);
echo "Stored string in redis:: "
print_r($arList);
?>
当执行程序时,会产生下面的结果:
Connection to server sucessfully
Stored string in redis::
Redis
Mongodb
Mysql
Redis的PHP键例
<?php
//Connecting to Redis server on localhost
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
echo "Connection to server sucessfully";
// Get the stored keys and print it
$arList = $redis->keys("*");
echo "Stored keys in redis:: "
print_r($arList);
?>
当执行程序时,会产生下面的结果:
Connection to server sucessfully
Stored string in redis::
tutorial-name
tutorial-list
