我在加入 2 个函数时遇到问题，所以我使用https://github.com/spatie/pdf-to-image - 此函数用于将上传的 pdf 转换为图像。这工作正常，但是此功能将转换后的图像上传到本地目录，但我想更改它并将转换后的图像保存到 yandex 磁盘而不是本地目录。我的 curl 用于将文件上传到 yandex 磁盘的功能也可以正常工作，但我不知道如何加入这两个功能，
我想改成$pdf->setPage($pageNumber)->saveImage($pageNumber . '.jpg');上传uploadtoyandexdisk("folder", "", $pageNumber . '.jpg');到yandex磁盘，你能帮忙吗？
//修改后的代码
if(!empty($_FILES["fileToUpload"])){
error_reporting(E_ALL);
ini_set("display_errors", 1);
function uploadtoyandexdisk($folder, $file, $name) {
if(empty($file)){
$filename = $name;
$filepath = $_FILES["fileToUpload"]["tmp_name"];
} else{
$filename = $name;
$filepath = $file;
}
$yandexusername = "username";
$yandexpassword = "password";
$credentials = array($yandexusername,$yandexpassword);
$filesize = filesize($filepath);
$fh = fopen($filepath, 'r');
$remoteUrl = 'https://webdav.yandex.ru/uploads/'.$folder.'/';
$ch = curl_init($remoteUrl . $filename);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, implode(':', $credentials));
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_INFILE, $fh);
curl_setopt($ch, CURLOPT_INFILESIZE, $filesize);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$response=curl_exec($ch);
fclose($fh);
echo $response;
