打开本地文件,并将其上传(非阻塞)到 FTP 服务器上的文件:
<?php
// connect and login to FTP server
$ftp_server = "ftp.example.com";
$ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");
$login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass);
$server_file = "serverfile.txt";
// open local file
$local_file = "localfile.txt";
$fp = fopen($local_file,"r");
// initiate upload
$d = ftp_nb_fput($ftp_conn, $server_file, $fp, FTP_BINARY)
while ($d == FTP_MOREDATA)
{
// do whatever you want
// continue uploading
$d = ftp_nb_continue($ftp_conn);
}
if ($d != FTP_FINISHED)
{
echo "Error uploading $local_file";
exit(1);
}
// close connection
ftp_close($ftp_conn);
?>
ftp_nb_fput() 函数将打开的本地文件上传到 FTP 服务器(非阻塞)。
提示:此功能(与ftp_fput()) 异步检索文件,因此您可以在下载文件时执行其他操作。
ftp_nb_fput(
ftp_conn, remote_file, open_file, mode, startpos);
