如何分隔具有相同值和不同值的php数组
如何分隔具有相同值和不同值的php数组
提问于 2013-05-17 17:36:38
我有一个购物篮，里面有例如6件商品。有些商品是一家商店的商品，另一种商品是一家商店的商品，甚至可能是两家商店的商品。
我希望为每个商店创建因子。我该怎么做呢？我怎么知道篮子里的这些东西是一个店铺的，还是两个或三个店铺的。如何才能将这一项分离到因子。
Array('customer' => Array('basket' => Array(
'9_2' => Array
(
"row" => "0",
'item' => 'cd',
'count' => '1',
'sale_start_date' => '1391-12-25 19:27:56',
'sale_end_date' => '1392-04-20 19:27:49',
'sale_price' => '40500',
'price' => '54564',
'id' => '999035',
'shopid' => '4'
),
'999_17' => Array
(
'row' => '1',
'item' => 'car',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '6'
),
'9_3' => Array
(
'row' => '2',
'item' => 'book',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '4'
),
'10_5' => Array
(
'row' => '2',
'item' => 'dvd',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '5'
)
)
)
);这个例子是我会话中的数组。我想要与购物价值分开的因素。例如，在这个篮子中，我们有来自shopid=4的2个项目，来自shopid=6的1个项目和来自shopid=5的一个项目，如何为每个商店创建单独的因素。
首先，我使用usort函数对带有shop I的排序数组进行排序，但是我不能继续为create factor分离每个相同和不相同的商品。

像这样的东西应该是可行的
<?php
$shopItems = array();
foreach ($_SESSION['customer']['basket'] as $basket) {
$key = $basket['shopid'];
$shopItems[$key][] = $basket;
}这将在数组$shopItems的元素中存储来自同一商店id的多组商品
例如(仅显示商店id 4)
Array (
[4] => Array (
[0] => array(
"row" => "0",
'item' => 'cd',
'count' => '1',
'sale_start_date' => '1391-12-25 19:27:56',
'sale_end_date' => '1392-04-20 19:27:49',
'sale_price' => '40500',
'price' => '54564',
'id' => '999035',
'shopid' => '4'
),
[1] => array(
'row' => '2',
'item' => 'book',
'count' => '1',
'sale_start_date' => '0000-00-00 00:00:00',
'sale_end_date' => '0000-00-00 00:00:00',
'sale_price' => '0',
'price' => '520000',
'id' => '999039',
'code' => 'b125nh',
'shopid' => '4'
)

$basket = array();
foreach ($_SESSION['customer']['basket'] as $k => $v)
$basket[$v['shopid']][$k] = $v;
print_r($basket);结果：

这应该能起到作用。
function get_seperated_shops($all_items)
{
$seperated_shops = array();
foreach($all_items AS $item => $properties)
{
$seperated_shops[$properties['shopid']][$item] = $properties;
}
return $seperated_shops;
}
echo "<pre>";
print_r(get_seperated_shops($_SESSION['customer']['basket']));
echo "</pre>";页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
