使用foreach循环PHP将多维数组转换为POST调用

function convertArrayToPost($array, $prefix = '') {
    $postFields = array();
    
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            $postFields = array_merge($postFields, convertArrayToPost($value, $prefix . $key . '_'));
        } else {
            $postFields[$prefix . $key] = $value;
        }
    }
    
    return $postFields;
}

// 示例多维数组
$array = array(
    'name' => 'John Doe',
    'age' => 30,
    'address' => array(
        'street' => '123 Main St',
        'city' => 'New York',
        'state' => 'NY'
    )
);

// 转换为POST调用的数组
$postData = convertArrayToPost($array);

// 发送POST请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/api');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// 处理响应
if ($response === false) {
    echo 'POST request failed.';
} else {
    echo 'POST request successful. Response: ' . $response;
}
