从同一阵列与别人比较值的数组值 [英] Compare array values with others values from the same array
本文介绍了从同一阵列与别人比较值的数组值的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想要实现的是，它会循环槽的阵列。然后，它会看，如果阵列中的项目是关于三个点是相同的：PRODUCT_ID，尺寸值和颜色值。
我想创造一个项目都列一个新的数组，我不希望的唯一的事情就是重复值。我想了重复的值，如果他们在这三个点的数量将一起计算相同的。就像如果我有3项相同的产品ID相同的尺寸和相同的颜色和三者并重的我下令我的新阵列3项这只是站在1时间和数量将是9于是就有了我新的不重复值数组。
电流回路
的foreach（$订单为$关键=＆GT; $顺序）{
的foreach（$秩序['orderProducts']为$关键=＆GT; $值）{
呼应'＆LT; pre＆GT;';
的print_r（$值['属性']）;
呼应'＆LT; / pre＆GT;';
}
}
结果如下数组
阵列
（
[ID] =＆GT; 2
[PRODUCT_ID] =＆GT; 4
[ORDER_ID] =＆GT; 2
[名] =＆GT; swag3
[说明] =＆GT;哈哈
[价格] =＆GT; 19.95
[收益] =＆GT; 10.00
[数量] =＆GT; 2
[属性] =＆GT; [{ID：1，名：大小，值：XS，主动：1}，{ID：8，名：颜色，价值： 才子，主动：1}]
）
排列
（
[ID] =＆GT; 3
[PRODUCT_ID] =＆GT; 3
[ORDER_ID] =＆GT; 3
[名] =＆GT; swag2
[说明] =＆GT;大声笑
[价格] =＆GT; 19.95
[收益] =＆GT; 10.00
[数量] =＆GT; 2
[属性] =＆GT; [{ID：2，名：大小，值：S，主动：1}，{ID：7，名：颜色，价值： 兹瓦特，活性：1}]
）
排列
（
[ID] =＆GT; 4
[PRODUCT_ID] =＆GT; 3
[ORDER_ID] =＆GT; 4
[名] =＆GT; swag2
[说明] =＆GT;大声笑
[价格] =＆GT; 19.95
[收益] =＆GT; 10.00
[数量] =＆GT; 1
[属性] =＆GT; [{ID：2，名：大小，值：S，主动：1}，{ID：7，名：颜色，价值： 兹瓦特，活性：1}]
）
排序的我要找的。

解决方案
注意它的刀片PHP作为前端。
后端
$为了//与产品行列
$项= [];
的foreach（$订单为$关键=＆GT; $顺序）{
的foreach（$秩序['orderProducts']为$ OP）{
$ I = [
'产品'= GT;产品:: findOrFail（$ OP-GT＆; PRODUCT_ID） - GT;的toArray（）
'属性'=＆GT; $ OP-GT＆;属性，
量= GT; $ OP-GT＆;数量
];
$ matchedResult = FALSE;
$数= COUNT（$项目）;
为（$ A = 0; $ A＆LT; $计数; $一个++）{
//使用$项数组在同一PRODUCT_ID项目
如果（$项目[$一] ['产品'] ['身份证'] == $ I ['产品'] ['身份证']）{
//检查属性也相同
如果（$项目[$一] ['属性'] === $ I ['属性']）{
//属性AR埃特相同的，所以补上
$项目[$一] ['量'] + = $ I ['量'];
$ matchedResult =真;
继续; //如果其右侧没有其他比赛
}
}
}
如果（$ matchedResult === FALSE）{
//仅当存在不匹配推项目。
$项目[] = $ I;
}
}
}
前端
＆LT; DIV CLASS =表响应＆GT;
＆LT;表类=表的表条纹＆GT;
＆LT;＆THEAD GT;
＆所述; TR＆GT;
＆LT;第i产品与LT; /第i
＆LT;第i量和LT; /第i
＆LT; / TR＆GT;
＆LT; / THEAD＆GT;
＆LT;＆TBODY GT;
@foreach（$项目为$项）
＆所述; TR＆GT;
＆LT; TD＆GT; {{$项目[产品] [名称]}}
@if（计数（$项目['属性']）0）＆LT;小＆GT;
@foreach（$项目['属性']为$ ATT）
{{$ ATT [名称]}} - {{$ ATT ['值']}}
@endforeach
＆LT; /小＆GT;
@ ENDIF＆LT; / TD＆GT;
＆LT; TD＆GT; {{$项目[数量]}}＆LT; / TD＆GT;
＆LT; / TR＆GT;
@endforeach
＆LT; / TBODY＆GT;
＆LT; /表＆gt;
＆LT; / DIV＆GT;
解决方案
您可以实现自己的目标，而无需使用嵌套循环。您可以使用的PRODUCT_ID，大小和颜色参数散列函数，并使用该值作为这样一个新的数组键：
$ =订单//原数组;
$ newOrders = []; //新数组的foreach（$订单为$顺序）{
$ PI = $秩序[的product_id]; //获取PRODUCT_ID
$ ATTR = json_de code（$秩序[属性]）; //获取属性：
$大小= $ ATTR [0] - ＆GT;价值; //获取大小值
$颜色= $ ATTR [1] - ＆GT;颜色; //获取颜色 $哈希= sprintf的（％s％s％S。$ PI，$大小，颜色$）; //计算散列 如果（$ newOrders [$哈希]）{
$ newOrders [$哈希] .quantity ++; //如果散列已经present然后只是增加量
}其他{
//否则添加新秩序
$ newOrders [$哈希] = [
命令=＆GT; $秩序，
量= GT; 1
];
}
}
What I’m trying to achieve is that, it will loop trough the array. Then it will look if the items in the array are the same on three points: product_id, the size value and the color value. I want to create a new array where the items are listed, the only thing I don’t want is the duplicated values. I want that the duplicated values if they are the same on those three points that the quantity will be count together. Like if I have 3 items same product id same size and same color and both of the three I ordered 3 items in my new array this is just standing 1 time and the quantity will be 9. So there will be no duplicated values in my new array.
Current loop
foreach($orders as $key => $order){
foreach($order['orderProducts'] as $key => $value){
echo '<pre>';
print_r($value['attributes']);
echo '</pre>';
}
}
results in the the following array
Array
(
[id] => 2
[product_id] => 4
[order_id] => 2
[name] => swag3
[description] => haha
[price] => 19.95
[proceeds] => 10.00
[quantity] => 2
[attributes] => [{"id":1,"name":"Size","value":"XS","active":1},{"id":8,"name":"Color","value":"Wit","active":1}]
)
Array
(
[id] => 3
[product_id] => 3
[order_id] => 3
[name] => swag2
[description] => lol
[price] => 19.95
[proceeds] => 10.00
[quantity] => 2
[attributes] => [{"id":2,"name":"Size","value":"S","active":1},{"id":7,"name":"Color","value":"Zwart","active":1}]
)
Array
(
[id] => 4
[product_id] => 3
[order_id] => 4
[name] => swag2
[description] => lol
[price] => 19.95
[proceeds] => 10.00
[quantity] => 1
[attributes] => [{"id":2,"name":"Size","value":"S","active":1},{"id":7,"name":"Color","value":"Zwart","active":1}]
)
Sort of what I’m looking for..
Array
(
[id] => 2
[product_id] => 4
[order_id] => 2
[name] => swag3
[description] => haha
[price] => 19.95
[proceeds] => 10.00
[quantity] => 2
[attributes] => [{"id":1,"name":"Size","value":"XS","active":1},{"id":8,"name":"Color","value":"Wit","active":1}]
)
Array
(
[id] => 3
[product_id] => 3
[order_id] => 3
[name] => swag2
[description] => lol
[price] => 19.95
[proceeds] => 10.00
[quantity] => 3
[attributes] => [{"id":2,"name":"Size","value":"S","active":1},{"id":7,"name":"Color","value":"Zwart","active":1}]
)
Solution Note it's blade php as frontend.
Backend
$order // is the array with products
$items = [];
foreach($orders as $key => $order){
foreach($order['orderProducts'] as $op){
$i = [
'product'=> Product::findOrFail($op->product_id)->toArray(),
'attributes' =>$op->attributes,
'quantity'=>$op->quantity
];
$matchedResult = false;
$count = count($items);
for($a = 0; $a < $count; $a++){
// Items with the same product_id in the $item array
if($items[$a]['product']['id'] == $i['product']['id']){
//check if the attributes are also the same
if($items[$a]['attributes'] === $i['attributes']){
// The attributes ar ethe same so up the quantity
$items[$a]['quantity'] += $i['quantity'];
$matchedResult = true;
continue; // If its right there are no other matches
}
}
}
if($matchedResult === false){
// only push item if there is not a match.
$items[] = $i;
}
}
}
Frontend
<div class="table-responsive">
<table class="table table-striped">
<thead>
<tr>
<th>Product</th>
<th>quantity</th>
</tr>
</thead>
<tbody>
@foreach($items as $item)
<tr>
<td>{{$item['product']['name']}}
@if(count($item['attributes']) > 0) <small>
@foreach($item['attributes'] as $att)
{{$att['name']}} - {{$att['value']}}
@endforeach
</small>
@endif</td>
<td>{{$item['quantity']}}</td>
</tr>
@endforeach
</tbody>
</table>
</div>
解决方案
You can achieve your goal without using nested loops. You may use hash function of product_id, size and color parameters and use that value as a new array key like this:
$orders = // original array;
$newOrders = []; // new array
foreach($orders as $order) {
$pi = $order["product_id"]; // get product_id
$attr = json_decode($order["attributes"]); // get attributes:
$size = $attr[0]->value; // get size value
$color = $attr[1]->Color; // get color
$hash = sprintf("%s.%s.%s", $pi, $size, $color); // Calculate hash
if ($newOrders[$hash]) {
$newOrders[$hash].quantity++; // If hash is already present then just increase quantity
} else {
// Otherwise add new order
$newOrders[$hash] = [
"order" => $order,
"quantity" => 1
];
}
}
