This article mainly introduces the sharing of a simple example of PHP using redis. It is mainly to show you how to use redis in PHP. If necessary Friends, please refer to it.

The example is very simple and has been explained in the comments, so there won’t be much nonsense here.

The code is as follows:

/*Get the database name from the platform*/
$dbname = "";
/*Get host, port, user, pwd from environment variables*/
$host = '';
$port = '';
$user = '';
$pwd = '';
try {
/*After establishing the connection, auth verification is required before performing the collection operation*/
$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());
}
/*Then you can operate the library. For specific operation methods, please refer to the phpredis official documentation*/
$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());
}
?>
