我有一个名为$json的数组，有47个子数组。在这些子数组中，有一个[company]字段。其中15个子阵列有一个空的[company]字段。
因此，要填充这些空的[company]字段，我会使用网站根据[mac]字段搜索公司名称。以下丑陋的黑客完成了工作：
foreach ($json as $key=>$field)
{
if (empty($field['company']))
{
$emptyCompany[] = $field['company'];
$companyFinder = file_get_contents('http://www.adminsub.net/mac-address-finder/'.$field['mac']);
$html = htmlspecialchars($companyFinder);
$cutFrom = "www.google.com/search?q=";
$cutTo = """;
$sub = substr($html, strpos($html, $cutFrom) + strlen($cutFrom), strlen($html));
$newCompany[] = substr($sub, 0, strpos($sub, $cutTo));
}
}
以下是相关阵列。
使用print_r($emptyCompany)清空公司数组，仅供参考：

我的问题是：如何正确地将$newCompany数组中的新公司值添加到$json数组？。我尝试使用push_array()和push_merge()，但我无法使用它。
答案 0 :(得分：2)
您可以直接在循环中添加值
$json[$key]['company'] = substr($sub, 0, strpos($sub, $cutTo));
如果无法做到这一点，请确保您的$newCompany - 数组已编入$key索引，然后合并数组：
// Option 1 - use this line in the loop and then loop through the created array
$newCompany[$key] = substr($sub, 0, strpos($sub, $cutTo));
foreach($newCompany as $key => $value){
$json[$key]['company'] = $value;
}
// Option 2 - use this line in the loop and use array_merge_recursive
$newCompany[$key] = ['company' => substr($sub, 0, strpos($sub, $cutTo))];
array_merge_recursive($json, $newComany);
我不完全确定array_merge_recursive将如何处理它。在使用之前，你一定要测试一下！
