给出 serialize 的结果(不要截图)


array (size=2)
  0 => 
    array (size=16)

      0 => 
        array (size=6)
          'rule_1' => 
            array (size=3)
              ...

      1 => 
        array (size=6)
          'rule_1' => 
            array (size=3)
              ...
          'piece' => string '3' (length=1)

      'shopid' => string '319' (length=3)
      'num' => string '5' (length=1)

      'volume' => string '3' (length=1)
      'unit' => string '1' (length=1)

其中 
第一条



array (size=3)
  1 => string '2' (length=1)
  2 => string '304' (length=3)
  3 => string '2' (length=1)

array (size=3)
  1 => string '3' (length=1)
  2 => string '309' (length=3)
  3 => string '1' (length=1)

第二条rule_1 是


array (size=3)
  1 => string '2' (length=1)
  2 => string '128' (length=3)
  3 => string '3' (length=1)

既然你喜欢瞒满抗抗的,也就罢了
观察到 rule_1 属于 第三维的关联键,你就弄个二重循环遍历一下就是了



求教
弄个二重循环遍历一下
怎么整?  确实数据不怎么好友

循环出来都麻烦,这个是用在,订单中,每个商品的促销规则不一样,有一个有两个的

没有数据怎么写代码?
难不成还要我给你造些数据?

出来了,谢谢

$nn = 0;			foreach($shop_list as $key=>&$val){					for($i=0;$i<count($shop_list);$i++){					if($shop_list[$key][$i]['rule_1']){						var_dump("99999");						$nn = $nn + 1;										}																					}					$shop_list[$key]['rule_nu'] = $nn; 					$nn = 0;												}			var_dump($shop_list);
Copy after login



大神级别的人都喜欢模拟 数据

谢了, 出来了 出来了

不是喜欢 喜欢模拟数据
而是既然在教你如何做,就必须给能通过测试的代码
糊弄你有什么意思

谢谢 ~~~
