PHP5中文手册·Retrieves a file from the FTP server and writes it to an open file (non-blocking) -- 追寻梦想＞编程乐园＞PHP 编程

说明

int ftp_nb_fget ( resource $ftp_stream , resource $handle , string $remote_file , int $mode [, int $resumepos ] )

ftp_nb_fget() retrieves a remote file from the FTP server.

The difference between this function and ftp_fget() is that this function retrieves the file asynchronously, so your program can perform other operations while the file is being downloaded.

参数

ftp_stream: The link identifier of the FTP connection.
handle: An open file pointer in which we store the data.
remote_file: The remote file path.
mode: The transfer mode. Must be either FTP_ASCII or FTP_BINARY.
resumepos

返回值

Returns FTP_FAILED or FTP_FINISHED or FTP_MOREDATA.

范例

<?php

// open some file for reading

$fp = fopen($file, 'w');

$conn_id = ftp_connect($ftp_server);

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

// Initate the download
$ret = ftp_nb_fget($conn_id, $fp, $file, FTP_BINARY);
while ($ret == FTP_MOREDATA) {

   // Do whatever you want
   echo ".";

   // Continue downloading...
   $ret = ftp_nb_continue($conn_id);
}
if ($ret != FTP_FINISHED) {
   echo "There was an error downloading the file...";
   exit(1);
}

// close filepointer
fclose($fp);
?>
