尝试根据匹配值从两个对象数组创建一个新数组，但不知道如何实现。
$dData = '[
{
"products": [
{
"Part ID" : "001",
"name" : "Product Name",
"category" : "Product Category",
"description" : "Product Description",
"id" : "111xyz",
},
{
"Part ID" : "002",
"name" : "Product Name 2",
"category" : "Product Category 2",
"description" : "Product Description 2",
"id" : "333xyz"
},
{
"Part ID" : "003",
"name" : "Product Name 3",
"category" : "Product Category 3",
"description" : "Product Description 3",
"id" : "444xyz"
},
{
"Part ID" : "004",
"name" : "Product Name 4",
"category" : "Product Category",
"description" : "Product Description",
"id" : "666xyz",
"features_img_id":["f1","f2","f3"]
}]
},
{
"assets": [
{
"File Name" : "Some file name",
"url" : "www.123.com/x.jpg",
"id" : "111xyz"
},
{
"File Name" : "Feature 1 file",
"url" : "www.123.com/f1.jpg",
"id" : "f1"
},
{
"File Name" : "Feature 2 file",
"url" : "www.123.com/f2.jpg",
"id" : "f2"
},
{
"File Name" : "Feature 2 file",
"url" : "www.123.com/f3.jpg",
"id" : "f3"
}]
}
]';
所需的新数组结果
Array
(
[0] => stdClass Object
(
[Part ID] => 001
[name] => Product Name 1
[category] => Product Category
[description] => Product Description
[url] => www.123.com/x.jpg
)
[1] => stdClass Object
(
[Part ID] => 002
[name] => Product Name 2
[category] => Product Category 2
[description] => Product Description 2
)
[2] => stdClass Object
(
[Part ID] => 003
[name] => Product Name 3
[category] => Product Category 3
[description] => Product Description 3
)
[3] => stdClass Object
(
[Part ID] => 004
[name] => Product Name 4
[category] => Product Category 4
[description] => Product Description 4
[feature_img-url] => Array
(
[0] => www.123.com/f1.jpg
[1] => www.123.com/f3.jpg
[2] => www.123.com/f3.jpg
)
)
)
下面是我尝试过的方法，但它只产生一个数组
$data = json_decode($dData, false);
$products = $data[0]->products;
$assets = $data[1]->assets;
$newArr;
foreach ($products as $key => $value) {
$newArr = $value->features_img;
}
$processedProducts = $products;
foreach ($processedProducts as $key => $product) {
foreach ($assets as $asset) {
if ($asset->id == $product->id) {
$product->url = $asset->url;
} elseif ($asset->id == in_array($asset->id, $newArr)) {
$product->features_image_url = $asset->url;
} else {
//code
}
}
unset($product->id);
}
print_r($processedProducts);
如果我完全是新手，我要道歉。不知道如何定位'feature_img_id'数组并将其与资产ID匹配并将其添加到$ processedProducts中。请查看所需的结果以获取想法。
答案 0 :(得分：1)
您可以这样做：
$dData = '[
{
"products": [
{
"Part ID" : "001",
"name" : "Product Name",
"category" : "Product Category",
"description" : "Product Description",
"id" : "111xyz"
},
{
"Part ID" : "002",
"name" : "Product Name 2",
"category" : "Product Category 2",
"description" : "Product Description 2",
"id" : "333xyz"
},
{
"Part ID" : "003",
"name" : "Product Name 3",
"category" : "Product Category 3",
"description" : "Product Description 3",
"id" : "444xyz"
},
{
"Part ID" : "004",
"name" : "Product Name 4",
"category" : "Product Category",
"description" : "Product Description",
"id" : "666xyz",
"features_img_id":["f1","f2","f3"]
}]
},
{
"assets": [
{
"File Name" : "Some file name",
"url" : "www.123.com/x.jpg",
"id" : "111xyz"
},
{
"File Name" : "Feature 1 file",
"url" : "www.123.com/f1.jpg",
"id" : "f1"
},
{
"File Name" : "Feature 2 file",
"url" : "www.123.com/f2.jpg",
"id" : "f2"
},
{
"File Name" : "Feature 2 file",
"url" : "www.123.com/f3.jpg",
"id" : "f3"
}]
}
]';
$data = json_decode($dData, false);
$products = $data[0]->products;
$assets = $data[1]->assets;
$processedProducts = $products;
foreach($processedProducts as $key => $product) {
foreach($assets as $asset) {
if ($asset->id == $product->id) {
$product->url = $asset->url;
}
if (isset($product->features_img_id) && in_array($asset->id, $product->features_img_id)) {
$product->feature_image_url[] = $asset->url;
}
}
unset($product->id);
unset($product->features_img_id);
}
将导致下面的结果数组：
Array
(
[0] => stdClass Object
(
[Part ID] => 001
[name] => Product Name
[category] => Product Category
[description] => Product Description
[url] => www.123.com/x.jpg
)
[1] => stdClass Object
(
[Part ID] => 002
[name] => Product Name 2
[category] => Product Category 2
[description] => Product Description 2
)
[2] => stdClass Object
(
[Part ID] => 003
[name] => Product Name 3
[category] => Product Category 3
[description] => Product Description 3
)
[3] => stdClass Object
(
[Part ID] => 004
[name] => Product Name 4
[category] => Product Category
[description] => Product Description
[feature_image_url] => Array
(
[0] => www.123.com/f1.jpg
[1] => www.123.com/f2.jpg
[2] => www.123.com/f3.jpg
)
)
)
