PHP显示ftp_get的进度百分比？ [英] PHP Display a percentage of progress of ftp_get?

问题描述

我有一个可用的FTP文件下载脚本。

我正在下载的文件大约每天2-4 GB。

我想知道是否有办法获取文件所在的百分比？

我已经查看了php.net和这里，但我找不到任何类似的问题，而是花更多的时间寻找我想我会问人们比我更聪明。

我在想如果有一个函数可以看到它下载的位置，但我找不到一个是因为 ftp_get 必须先完成，这样就消除了每隔几秒刷新缓冲区以显示新百分比的机会。

任何人？

以下是我的代码：我将所有变量隐藏在上面。

  $ conn_id = ftp_connect（$ ftp_server）; 
 
 $ login_result = ftp_login（$ conn_id，$ ftp_user_name，$ ftp_user_pass）; 
 $ b $ if（ftp_get（$ conn_id，$ local_file，$ server_file，FTP_BINARY））{
 echo成功写入$ local_file \ n; 
} else {
 echoThere's a problem \\\
; 
} 
 
 ftp_close（$ conn_id）; 
  

---

编辑：

我添加了 ftp_nb_get ，这里是我的代码。
$ b

  $ ret = ftp_nb_get（$ conn_id，$ local_file ，$ server_file，FTP_BINARY，$ size）; 
 while（$ ret == FTP_MOREDATA）{
 echo round（（filesize（$ local_file）/ $ server_size）* 100）。％\ n; 
 $ ret = ftp_nb_continue（$ conn_id）; 
 
  

解决方案

尝试使用非阻塞版本 ftp_nb_get（） 和 ftp_nb_continue（ ） ，并检查保存的文件的大小。

I have a working FTP file download script.
The files I am downloading will be about 2-4 GB per day.
I was wondering if there was a way to get the percent of the file where it's at?

I have looked on php.net and on here but I couldn't find any similar questions and rather spend more time looking I figure I would ask people much smarter than myself.

I was thinking about if there was a function to see where it's at in the download, but I couldn't find one since ftp_get would have to complete first so that eliminated the chance of flushing the buffer every few seconds to display a new percent.

Anyone?

Here is my code: I hid all of my variables above it.

$conn_id = ftp_connect($ftp_server);

$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
} else {
    echo "There was a problem\n";
}

ftp_close($conn_id);

EDIT:

I added ftp_nb_get and here is my code for that. It keeps downloading fine, just doesn't echo it out to the browser.

$ret = ftp_nb_get($conn_id, $local_file, $server_file, FTP_BINARY, $size);
while ($ret == FTP_MOREDATA) {
  echo round((filesize($local_file)/$server_size)*100)."%\n";
  $ret = ftp_nb_continue($conn_id);
}

解决方案

Try using the non-blocking version ftp_nb_get() and ftp_nb_continue() in a loop, and check for the saved file's size.
