swoole使用内存

    //swoole直接操做系统的内存 单线程每秒可执行三百万次  主要用于进程间的数据通讯    $swoole_table = new swoole_table(1024);//1024为内建立内存对象所能存储的最大行数    //建立内存表的字段    $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']);    //表内某一值增长    $swoole_table->incr('zonehoo_2','age','2');    print_r($swoole_table['zonehoo_2']);    //表内某一值减    $swoole_table->decr('zonehoo_2','age','1');    print_r($swoole_table['zonehoo_2']);
