PHP 使用redis简单示例分享

<?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($redis->getLastError());
????}
????/*接下来就可以对该库进行操作了,具体操作办法请参考phpredis官方文档*/
????$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());
}
?>
