//创建内存表
$table = new swoole_table(1024);

//内存添加一列
$table->column('id', $table::TYPE_INT, 4);
$table->column('name', $table::TYPE_STRING, 64);
$table->column('age', $table::TYPE_INT, 4);
$table->create();

$table->set('wawa_detail', ['id' => 1, 'name' => 'name', 'age' => 6]);
print_r($table->get('wawa_detail'));

场景：多进程序之间共享数据

//创建内存表
$table = new swoole_table(1024);

//内存添加一列
$table->column('id', $table::TYPE_INT, 4);
$table->column('name', $table::TYPE_STRING, 64);
$table->column('age', $table::TYPE_INT, 4);
$table->create();

$table->set('wawa_detail', ['id' => 1, 'name' => 'name', 'age' => 6]);
print_r($table->get('wawa_detail')); //输出的是数据

//set get另外一种方式
$table['wawa_details'] = [
    'id' => 1,
    'name' => 'name',
    'age' => 5
];
print_r($table['wawa_details']); //输出的是对象

//对里面某个参数进行加数字操作，这时AGE应该是8， 原子自加操作。
$table->incr('wawa_details', 'age', 3);
print_r($table['wawa_details']); //输出的是对象
//原子自减操作。
$table->decr('wawa_details', 'age', 2);
print_r($table['wawa_details']); //输出的是对象
//删除
echo 'del start:'.PHP_EOL;
$table->del('wawa_details');
print_r($table['wawa_details']);

//等等，可见官方文档
