如何仅从curl(php)中获取具有特定值的键名

<?php
// 初始化curl会话
$curl = curl_init();

// 设置curl选项
curl_setopt($curl, CURLOPT_URL, "http://example.com/api"); // 设置请求URL
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); // 将响应作为字符串返回

// 执行请求并获取响应
$response = curl_exec($curl);

// 关闭curl会话
curl_close($curl);

// 解析JSON响应
$data = json_decode($response, true);

// 遍历解析后的数据，查找具有特定值的键名
$targetValue = "specific value";
$targetKeys = [];

function findKeys($data, $targetValue, &$targetKeys) {
    foreach ($data as $key => $value) {
        if ($value === $targetValue) {
            $targetKeys[] = $key;
        } elseif (is_array($value) || is_object($value)) {
            findKeys($value, $targetValue, $targetKeys);
        }
    }
}

findKeys($data, $targetValue, $targetKeys);

// 输出具有特定值的键名
foreach ($targetKeys as $key) {
    echo $key . "\n";
}
?>
