我有两个关联的多维数组 $ arrayOffered 和 $ arraySold 。我想在某些条件下合并它们:
$ arrayOffered 中的一个元素在 $ arraySold 中可以有> 1个等价物。它们应按以下方式连接。
输入数据:
$arrayOffered = array(
0 => array('item' => 'product_1', 'Category' => 'ABC'),
1 => array('item' => 'product_2', 'Category' => 'DEF')
);
$arraySold = array(
0 => array('item' => 'product_1', 'ItemsSold' => '2', 'ItemsReturned' => 1), //arrays in this array can contain up to 30 elements
1 => array('item' => 'product_1', 'ItemsSold' => '1')
);
期望的结果:
$desiredResult = array(
0 => array('item' => 'product_1', 'Category' => 'ABC', 'ItemsSold' => '2', 'ItemsReturned' => 1),
1 => array('item' => 'product_1', 'Category' => 'ABC', 'ItemsSold' => '1'),
2 => array('item' => 'product_2', 'Category' => 'DEF')
);
我遇到了类似的问题:
$result = array();
foreach ($arrayOffered as $keyOffered => $offeredSubArr)
{
$item = $offeredSubArr['item'];
foreach($arraySold as $keySold => $soldSubArr)
{
if(isset($soldSubArr['item']) && $soldSubArr['item'] == $item)
{
$i = 0;
$test = array_merge($offeredSubArr, $soldSubArr);
$result[$i][] = $test;
$i++;
}
else
{
$result[$i][] = $offeredSubArr;
$i++;
}
}
}
问题:
- 输出数组没有按照我想要的方式格式化
- 我知道我没有朝着正确的方向前进。你能给我一个提示吗?

这是一个选项,因为你有这个$ arrayOffered作为一种主文件,我建议使用这个数组构建一个哈希值,稍后再使用foreach查找已售出的数组。
$arrayOffered = array(
0 => array('item' => 'product_1', 'Category' => 'ABC'),
1 => array('item' => 'product_2', 'Category' => 'DEF')
);
$arraySold = array(
0 => array('item' => 'product_1', 'ItemsSold' => '2', 'ItemsReturned' => 1), //arrays in this array can contain up to 30 elements
1 => array('item' => 'product_1', 'ItemsSold' => '1')
);
//Build a hash to get the extra properties
$hashArray = array();
foreach ($arrayOffered as $offered) {
$hashArray[$offered['item']]=$offered;
}
$resultArray = array();
foreach ($arraySold as $sold) {
$hashItem = $hashArray[$sold['item']];
// you dont want this sold flag on your final result
unset($hashItem['sold']);
$resultArray[]=array_merge($hashItem,$sold);
$hashArray[$sold['item']]['sold']= true;
}
//Add all the missing hash items
foreach($hashArray as $hashItem){
if(!isset($hashItem['sold'])){
$resultArray[]=$hashItem;
}
}
print_r($resultArray);

$result = array();
foreach ($arrayOffered as $keyOffered => $offeredSubArr)
{
$item = $offeredSubArr['item'];
foreach($arraySold as $keySold => $soldSubArr)
{ $i = 0;
if(isset($soldSubArr['item']) && $soldSubArr['item'] == $item)
{
$test = array_merge($offeredSubArr, $soldSubArr);
$result[$i][] = $test;
}
else
{
$result[$i][] = $offeredSubArr;
}
$i++;
}
}
$result = $result[0];
echo '<pre>'; print_r($result); die();

我会尝试遵循你的逻辑,尽管有更简单的解决方案。 首先,我们需要在多维数组中搜索,这就是为什么我们需要this so thread
后面的函数function in_array_r($needle, $haystack, $strict = false) {
foreach ($haystack as $item) {
if (($strict ? $item === $needle : $item == $needle) || (is_array($item) && in_array_r($needle, $item, $strict))) {
return true;
}
}
return false;
}
接下来经过小小的改动:
我们有以下代码:
$arrayOffered = array(
0 => array('item' => 'product_1', 'Category' => 'ABC'),
1 => array('item' => 'product_2', 'Category' => 'DEF')
);
$arraySold = array(
0 => array('item' => 'product_1', 'ItemsSold' => '2', 'ItemsReturned' => 1), //arrays in this array can contain up to 30 elements
1 => array('item' => 'product_1', 'ItemsSold' => '1')
);
$i = 0;
$result = array();
foreach ($arrayOffered as $keyOffered => $offeredSubArr)
{
$item = $offeredSubArr['item'];
foreach($arraySold as $keySold => $soldSubArr)
{
if(isset($soldSubArr['item']) && $soldSubArr['item'] == $item)
{
$test = array_merge($offeredSubArr, $soldSubArr);
$result[$i] = $test;
$i++;
}
}
}
foreach ($arrayOffered as $value)
{
if (!in_array_r($value['item'], $result))
{
$result[$i] = $value;
$i++;
}
}
print_r($result);
据我测试,这给出了想要的结果。
