swoole使用内存

    //swoole直接操作系统的内存 单线程每秒可执行三百万次  主要用于进程间的数据通信
    $swoole_table = new swoole_table(1024);//1024为内创建内存对象所能存储的最大行数
    //创建内存表的字段
    $swoole_table->column('id', $swoole_table::TYPE_INT, 4 );
    $swoole_table->column('name', $swoole_table::TYPE_STRING, 64 );
    $swoole_table->column('age', $swoole_table::TYPE_INT, 3);
    $swoole_table->create();

    //内存表内添加一列
    //第一个参数为key,第二个参数value
    $swoole_table->set('zonehoo',['id' =>'1','name'=>'zonehoo','age'=>'18']);
    //写成数组的形式
    $swoole_table['zonehoo_2'] = [
        'id' => 2,
        'name'  =>  'zonehoo2',
        'age'   =>  19,
    ];
    //获取
    print_r($swoole_table->get('zonehoo'));
//    print_r($swoole_table->get('zonehoo_2'));
    print_r($swoole_table['zonehoo_2']);
    //表内某一值增加
    $swoole_table->incr('zonehoo_2','age','2');
    print_r($swoole_table['zonehoo_2']);
    //表内某一值减
    $swoole_table->decr('zonehoo_2','age','1');
    print_r($swoole_table['zonehoo_2']);
