我有一個 json，我需要獲取特定值并使用 foreach 循環插入到數組中。然后我將它轉換回 json 以檢查我是否得到相同的數組/json 格式或輸出。但我無法讓它發揮作用。有人能幫助我嗎。謝謝！這是源格式：但這是我在 foreach 循環中生成的內容：這是我的代碼。$test_json= '{ "product": { "title": "Burton Custom Freestyle 151", "body_html": "<strong>Good snowboard!</strong>", "vendor": "Burton", "product_type": "Snowboard", "variants": [ { "option1": "Blue", "option2": "155" }, { "option1": "Black", "option2": "159" } ], "options": [ { "name": "Color", "values": [ "Blue", "Black" ] }, { "name": "Size", "values": [ "155", "159" ] } ] } }';$test_product = json_decode($test_json, true); $attributes2 = $test_product['product']['options'];$options_arr = array();foreach ($attributes2 as $attribute) {$options_arr['name'] = $attribute['name']; foreach ($attribute['values'] as $option) { $options_arr['values'][] = $option; } }$options_json = json_encode($options_arr);var_dump($options_json);

我認為這就是您要尋找的......這也沒有您的代碼那么復雜。
<?php
$test_json= '{ "product": { "title": "Burton Custom Freestyle 151", "body_html": "<strong>Good snowboard!</strong>", "vendor": "Burton", "product_type": "Snowboard", "variants": [ { "option1": "Blue", "option2": "155" }, { "option1": "Black", "option2": "159" } ], "options": [ { "name": "Color", "values": [ "Blue", "Black" ] }, { "name": "Size", "values": [ "155", "159" ] } ] } }';
$test_product = json_decode($test_json);
$options = $test_product->product->options;
// Check whatever you like in this for each
foreach ($options as $option) {
// Example
switch ($option->name) {
case 'Color':
echo 'this is the color array';
break;
}
}
$options_json = json_encode($options);
var_dump($options_json);
?>

如果我沒有誤解你的要求，那么你只需要這樣做就可以得到你想要的，
<?php
$test_json= '{ "product": { "title": "Burton Custom Freestyle 151", "body_html": "<strong>Good snowboard!</strong>", "vendor": "Burton", "product_type": "Snowboard", "variants": [ { "option1": "Blue", "option2": "155" }, { "option1": "Black", "option2": "159" } ], "options": [ { "name": "Color", "values": [ "Blue", "Black" ] }, { "name": "Size", "values": [ "155", "159" ] } ] } }';
$test_product = json_decode($test_json, true);
$attributes2 = $test_product['product']['options'];
$expected = ['options'=>$attributes2];
echo json_encode($expected);
?>

您正在覆蓋循環中的 name 鍵，您需要執行以下操作：
foreach ($attributes2 as $attribute) {
$data = [
"name" => $attribute["name"],
"values" => []
];
foreach ($attribute['values'] as $option) {
$data['values'][] = $option;
}
$options_arr[] = $data;
}
