Swoole和Workerman对PHP与MySQL的数据本地缓存和远程缓存的优化方法

<?php
// 创建一个内存表
$table = new swoole_table(1024);
$table->column('value', swoole_table::TYPE_STRING, 64);
$table->create();

// 设置缓存
$table->set('key1', ['value' => 'data1']);
$table->set('key2', ['value' => 'data2']);

// 获取缓存
$result = $table->get('key1');
echo $result['value']; // 输出：data1

<?php
$cache = [];
$cache['key1'] = ['value' => 'data1'];
$cache['key2'] = ['value' => 'data2'];

// 获取缓存
$result = $cache['key1'];
echo $result['value']; // 输出：data1

<?php
$redis = new swoole_redis;
$redis->connect('127.0.0.1', 6379, function ($redis, $result){
    if ($result === false) {
        // 连接失败处理
        return;
    }

    // 设置缓存
    $redis->set('key1', 'data1', function ($redis, $result){
        if ($result === false) {
            // 设置失败处理
            return;
        }

        // 获取缓存
        $redis->get('key1', function ($redis, $result){
            if ($result === false) {
                // 获取失败处理
                return;
            }

            echo $result; // 输出：data1
        });
    });
});

<?php
$memcached = new Memcached();
$memcached->addServer('localhost', 11211);

// 设置缓存
$memcached->set('key1', 'data1');

// 获取缓存
$result = $memcached->get('key1');
echo $result; // 输出：data1
