How to use Couchbase for data storage and query in Workerman

Introduction:
Workerman is a high-performance PHP asynchronous network programming framework, and Couchbase is An open source NoSQL database with high performance, scalability, and high availability. In this article, we will introduce how to use Couchbase for data storage and query in Workerman, and provide specific code examples.

1. Preparation work
Before using Couchbase, we need to do the preparation work:

1. Install Couchbase server
   First, we need to install Couchbase on the server . For specific installation methods, please refer to Couchbase official documentation.
2. Install Couchbase extension
   To use Couchbase in PHP, you need to install the corresponding extension. It can be installed through Pecl or compiled and installed manually. For specific installation methods, please refer to Couchbase official documentation.
3. Create Couchbase Bucket
   In Couchbase, data is stored in buckets. We need to create a bucket on the Couchbase server and record the bucket name, username, password and other information.

2. Connect to the Couchbase server
In Workerman, we can use the CouchbaseCluster class provided by the Couchbase PHP extension to connect to the Couchbase server. The following is a sample code to connect to the Couchbase server:

use CouchbaseCluster;

$cluster = new CouchbaseCluster('couchbase://127.0.0.1');
$bucket = $cluster->openBucket('your_bucket_name', 'your_bucket_username', 'your_bucket_password');

Among them, couchbase://127.0.0.1 is the address of the Couchbase server, your_bucket_name is the name of the bucket, your_bucket_username and your_bucket_password are the username and password of the bucket.

3. Store data
Using Workerman combined with Couchbase, we can use the relevant methods of the Bucket class provided by the Couchbase PHP extension to store data. The following is a sample code to store data into a Couchbase bucket:

use CouchbaseCluster;
use CouchbaseBucket;

$cluster = new CouchbaseCluster('couchbase://127.0.0.1');
$bucket = $cluster->openBucket('your_bucket_name', 'your_bucket_username', 'your_bucket_password');

$data = [
    'key' => 'value'
];

$key = 'your_key';
$bucket->upsert($key, $data);

where $data is the data to be stored, and $key is the key of the data. The upsert method is used to create or update data. If the key already exists, the original data will be updated.

4. Query data
Using Workerman combined with Couchbase, we can query data using the related methods of the Bucket class provided by the Couchbase PHP extension. The following is a sample code for querying data from a Couchbase bucket:

use CouchbaseCluster;
use CouchbaseBucket;

$cluster = new CouchbaseCluster('couchbase://127.0.0.1');
$bucket = $cluster->openBucket('your_bucket_name', 'your_bucket_username', 'your_bucket_password');

$key = 'your_key';
$result = $bucket->get($key);

if ($result->resultCode === CouchbaseBucket::RESULT_SUCCESS) {
    $data = $result->value;
    // 处理查询结果
} else {
    // 处理查询失败的情况
}

where $key is the key of the data to be queried. The get method is used to query data based on keys, and the query results will be encapsulated into an instance of the CouchbaseDocument class.

5. Summary
This article introduces how to use Couchbase for data storage and query in Workerman, and provides specific code examples. Through the combination of Workerman and Couchbase, high-performance and scalable data storage and query functions can be achieved, providing developers with a better development experience.

It should be noted that in actual use, we can also use other functions provided by Couchbase according to specific needs, such as batch operations, N1QL queries, etc. For more information, please refer to Couchbase official documentation.
