Swoole 是一个高性能的 PHP 异步网络通信引擎,可以用于构建高并发、低延迟的服务器应用程序。在使用 Swoole 开发 Redis 时,可以遵循以下技巧来提高开发效率和性能:
$pool = new Swoole\Coroutine\RedisPool('127.0.0.1', 6379, 10);
$pool->push('get', ['key' => 'value'], function ($result) {
echo "Result: $result\n";
});
$pool->push('pipeline', [
['set', ['key' => 'key1', 'value' => 'value1']],
['get', ['key' => 'key1']]
], function ($results) {
print_r($results);
});
$pool->push('get', ['key' => 'nonexistent_key'], function ($result) {
if ($result === false) {
echo "Key not found\n";
} else {
echo "Result: $result\n";
}
});
$pool->push('set', ['key' => 'key1', 'value' => 'value1'], function ($result) {
echo "Result: $result\n";
}, 5); // 设置 5 秒超时
$pool->push('get', ['key' => 'key1'], function ($result) {
echo "Result: $result\n";
});
// 确保在适当的位置释放连接池资源
$pool->close();
Swoole\Coroutine\run(function () use ($pool) {
$pool->push('set', ['key' => 'key1', 'value' => 'value1'], function ($result) {
echo "Result: $result\n";
});
});
class RedisClient {
private $pool;
public function __construct($host, $port, $size) {
$this->pool = new Swoole\Coroutine\RedisPool($host, $port, $size);
}
public function set($key, $value) {
return $this->pool->push('set', [$key, $value]);
}
public function get($key) {
return $this->pool->push('get', [$key]);
}
}
通过以上技巧,可以有效地提高使用 Swoole 开发 Redis 的性能和可维护性。
