試試這個。
$userData = [
[
"UID" => "5f10482574d83d4b726fe5",
"name" => "Yug Gill",
"orgID" => "5f10481d74d83d4b726",
"imageURL" => "female.png"
]
];
$userProductsData = [
[
"UPID" => "5f10482574d83d4b6fe007",
"UID" => "5f10482574d83d4b726fe5",
]
];
$userDetailsResult = [];
foreach ($userProductsData as $key => $value) {
$userData[$key]["UPID"] = $value['UPID'];
}
print_r($userData);

您$userProductsData是一個常規數組，它有索引 0、1、2 等...然后您嘗試通過字符串 key 從此數組中獲取項目"5f10482574d83d4b726fe5"。
$userProductsData應該是這樣的鍵數組：
$userProductsData = [
"5f10482574d83d4b726fe5" => [
"UPID" => "5f10482574d83d4b6fe007",
"UID" => "5f10482574d83d4b726fe5",
],
];
然后你可以通過 key 從這個數組中獲取一個項目"5f10482574d83d4b726fe5"。
