从FTP服务器下载文件并将其保存在本地文件中。

Posted 2021-02-25

I wrote this code for when I need to get files from other servers and put them on my own server. I wanted to simplify it as much as possible.

function ftp_download($ftp_host, $ftp_user, $ftp_pass, $remote_file_path, $local_file_path, $passive = true, $mode = FTP_BINARY) {
 
    $conn_id = ftp_connect($ftp_host);
 
    if ($conn_id) {
 
    if (@ftp_login($conn_id, $ftp_user, $ftp_pass)) {
 
    ftp_pasv($conn_id, $passive);
 
    if (ftp_get($conn_id, $local_file_path, $remote_file_path, $mode)) {
        ftp_close($conn_id);
        return true;
    } else {
        ftp_close($conn_id);
        return false;
    }
 
    } else {
      throw new Exception("Failed to login to the FTP server.", 100)
    }
 
    } else {
      throw new Exception("Failed to connect to the FTP server.", 99);
    }
 
}
