如何使用ftp連接通過PHP cURL上傳文件？

Question

我正在使用此腳本通過curl函數和ftp連接上傳myfile。

在本地工作正常，但在我的服務器文件中似乎已上傳，但文件大小為零。

怎么了？ 謝謝。

$ch = curl_init();
$localfile = (dirname(__FILE__).'/asset/myfile.zip');
$fp = fopen($localfile, 'r');
curl_setopt($ch, CURLOPT_URL, "ftp://$user_name:$user_pass@$server/".'myfile.zip');
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
curl_exec ($ch);
curl_close ($ch);

以及如何在此腳本中上傳多個文件，例如：

$localfile1 = (dirname(__FILE__).'/asset/myfile1.zip');
$localfile2 = (dirname(__FILE__).'/asset/myfile2.zip');
$localfile3 = (dirname(__FILE__).'/asset/myfile3.zip');

要使用curl上傳文件，可以使用curl_file_create。嘗試以下操作：

$localfile = (dirname(__FILE__).'/asset/myfile.zip');
$curl_file = curl_file_create($localfile,'zip');
$params = ['file' => $curl_file];

$ch = curl_init();
$localfile = (dirname(__FILE__).'/asset/myfile.zip');
$fp = fopen($localfile, 'r');
curl_setopt($ch, CURLOPT_URL, "ftp://$user_name:$user_pass@$server/".'myfile.zip');
curl_setopt($ch, CURLOPT_UPLOAD, 1);
//curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
curl_exec ($ch);
curl_close ($ch);
