在php程序中使用redis之前，需要确保在机器上安装了redis的php驱动程序和php环境。可以先在将php电脑上并配置好环境。本文就和大家分享php链接redis的方法代码，希望能帮助到大家。
安装
现在，让我们看看如何设置Redis PHP驱动程序。
从github库下载phpredis=> http://github.com/nicolasff/phpredis。 当下载它之后，提取文件到phpredis目录。在Ubuntu上，安装以下扩展。
cd phpredis sudo phpize sudo ./configure sudo make sudo make install
现在，将“modules”文件夹的内容复制并粘贴到PHP扩展目录中，并在php.ini中添加以下行。
extension = redis.so
现在，Redis PHP安装完成！

<?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(); ?>PHP
当程序执行时，将产生以下结果。
Connection to server sucessfully Server is running: PONG
<?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"); ?>执行上面代码，将生成以下结果 -
Connection to server sucessfully Stored string in redis:: Redis tutorial
<?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); ?>执行上面代码，将生成以下结果 -
Connection to server sucessfully Stored string in redis:: Redis Mongodb Mysql
<?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); ?>执行上面代码，将生成以下结果 -
Connection to server sucessfully Stored string in redis:: tutorial-name tutorial-list
