• swoole_table

#在内存中建立一张表，用来存放进程交互过程中使用的数据，与memocache似有异曲同工之妙
#用法

<?php
$table = new swoole_table(2048);
$table->column("id",$table::TYPE_INT,4);  #为内存表添加列
$table->column("name",$table::TYPE_STRING,32);
$table->column("age",$table::TYPE_INT,4);
$table->create(); #创建内存表
$table->set("cpc",["id"=>1,"name"=>"陈培昌","age"=>22]);
$table->set("cj",["id"=>2,"name"=>"程劲","age"=>16]);

$table->decr("cpc","age",1); #增加某一列的值
$table->incr("cj","age",2);  #扣减某一列的值
if ($table->exist("cpc"))  #判断键名是否存在

    print_r($table["cpc"]);


if ($table->exist("cj"))

    print_r($table->get("cj"));
