问题描述
不知道这是否可能,但在这里...我需要获取包含在对象中的数组的所有
索引

包含在 foreach中
var $ cart
包含一个 ARRAY
与多个索引
。如果我用 0
替换 $ x
,循环将显示 cart
数组。然而,一些购物车
包含多于> 1的索引。
$ b
count($ keys)
正确地回显了 cart
数组中索引的数目。例如,我有3辆车。
-
cart
1 has1 index
-
cart
2 has2 index
-
cart
3 has4 index
如果我做 echo count($ keys)
我得到 1 2 4
如何将每个循环的这些值(按顺序)分别传递给我的 $ x
var? / p>
请注意购物车可能具有多于一个的索引值
期望输出: / p>
每个 cart
包含一个包含多个产品的数组。 foreach必须迭代并显示 cart中的每个产品
基于上面显示的 cart $ c $的预期输出c>数组应该在如下表格中:
< tr> 0< / tr> / * cart 1在数组中有1个索引* /
< tr> 01< / tr> / * cart 2在数组中有2个索引* /
< tr> 0123< / tr> / * cart 3在数组中有4个索引* /
您可以尝试如下
您有每个订单可以有多个购物车,每个购物车有多个items.What你想要显示每个购物车的项目#。 / p>
<?php
cart = unserialize($ val-> cart);
$ keys = array_keys($ cart); //这会给你一个订单
//如果现在你要计算每个购物车的物品数量然后
foreach($键为$ val){
回声计数($购物[$ VAL]);
}
?>
Not sure if this is possible but here goes... i need to get all of the indexes
of an array contained within an object
foreach
<?php foreach($all_orders as $key => $val) : ?>
<?php
$cart = unserialize($val->cart);
$keys = array_keys($cart);
$x = count($keys);
$index = $keys[$x];
$cart = $cart[$index];
?>
<?php $val->field_name; ?>
<?php endforeach; ?>

This code is contained inside of a foreach
The var $cart
contains an object of an ARRAY
with multiple indexes
. If I replace $x
with 0
the loop will display the first index in the cart
array. However some cart
contain more than > 1 index.
count($keys)
is properly echoing out the number of indexes in the cart
array. For example I have 3 carts.
cart
1 has1 index
cart
2 has2 index
cart
3 has4 index
If i do echo count($keys)
I get back 1 2 4
How do I pass these values (in order) individually to my $x
var for each loop?
Notice how cart may have more than 1 index value
Expect Output:
Each cart
contains an array with multiple products. The foreach must iterate through and display each product in the array within cart
Based on the var_dump shown above the expected output of the cart
array should be in a table as follows:
<tr>0</tr> /*cart 1 has 1 index in the array*/
<tr>01</tr> /*cart 2 has 2 index in the array*/
<tr>0123</tr> /*cart 3 has 4 index in the array*/
You can give try as below
You have each order can have multiple carts and each cart have multiple items.What you want to display # of items into each cart.
<?php
$cart = unserialize($val->cart);
$keys = array_keys($cart); // this will give you # of carts into one order
//if now you want to count # of items into each cart then
foreach($keys as $val){
echo count($cart[$val]);
}
?>
