如何使用PHP调用快手API接口，实现视频的上传和编辑功能

<?php
// 定义API接口地址
$url = "https://open.kuaishou.com/video/upload";

// 定义APPID和Secret
$appId = "your_app_id";
$secret = "your_secret";

// 定义视频文件路径
$videoFilePath = "/path/to/your/video.mp4";

// 生成签名
$timestamp = time();
$signature = md5($appId . $secret . $timestamp);

// 构建请求参数
$data = array(
    "app_id" => $appId,
    "signature" => $signature,
    "timestamp" => $timestamp,
    "video" => new CURLFile(realpath($videoFilePath))
);

// 发起HTTP POST请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

// 解析返回结果
$response = json_decode($result, true);
if ($response && $response['result'] == 1) {
    // 上传成功
    $videoId = $response['video_id'];
    echo "上传成功，视频ID为：" . $videoId;
} else {
    // 上传失败
    $errorCode = $response['error_code'];
    $errorMsg = $response['error_msg'];
    echo "上传失败，错误码：" . $errorCode . "，错误消息：" . $errorMsg;
}
?>

<?php
// 定义API接口地址
$url = "https://open.kuaishou.com/video/edit";

// 定义APPID和Secret
$appId = "your_app_id";
$secret = "your_secret";

// 定义视频ID和新的标题
$videoId = "your_video_id";
$newTitle = "新的标题";

// 生成签名
$timestamp = time();
$signature = md5($appId . $secret . $timestamp);

// 构建请求参数
$data = array(
    "app_id" => $appId,
    "signature" => $signature,
    "timestamp" => $timestamp,
    "video_id" => $videoId,
    "title" => $newTitle
);

// 发起HTTP POST请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);

// 解析返回结果
$response = json_decode($result, true);
if ($response && $response['result'] == 1) {
    // 编辑成功
    echo "编辑成功";
} else {
    // 编辑失败
    $errorCode = $response['error_code'];
    $errorMsg = $response['error_msg'];
    echo "编辑失败，错误码：" . $errorCode . "，错误消息：" . $errorMsg;
}
?>
