PHP uses redis

<?php
/*从平台获取数据库名*/
$dbname = "";
 
/*从环境变量里取host,port,user,pwd*/
$host = '';
$port = '';
$user = '';
$pwd = '';
 
try {
    /*建立连接后，在进行集合操作前，需要先进行auth验证*/
    $redis = new Redis();
    $ret = $redis->connect($host, $port);
    if ($ret === false) {
	die($redis->getLastError());
    }
 
    $ret = $redis->auth($user . "-" . $pwd . "-" . $dbname);
    if ($ret === false) {
	die($redis->getLastError());
    }
 
    /*接下来就可以对该库进行操作了，具体操作方法请参考phpredis官方文档*/
    $redis->flushdb();
    $ret = $redis->set("key", "value");
    if ($ret === false) {
	die($redis->getLastError());
    } else {

	echo "OK".$redis->get("key");
    }
 
} catch (RedisException $e) {
    die("Uncaught exception " . $e->getMessage());
}
?>

　

The above introduces the use of redis in PHP, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
