When ftp files are stored in php, the file size is 0.

When uploading an ftp file through php, the file size is 0 $ user =$ _ COOKIE ['user']; $ passwd =$ _ COOKIE ['passwd']; $ current_dir = '/home/web/text'; $ conn_id = ftp_connect ("the file size is 0 when loc uploads ftp files through php.
$ User = $ _ COOKIE ['user'];
$ Passwd = $ _ COOKIE ['passwd'];
$ Current_dir = '/home/web/text ';
$ Conn_id = ftp_connect ("localhost", 21 );
$ Dir = $ _ REQUEST ['dir'];
If (@ ftp_login ($ conn_id, $ user, $ passwd ))
{
If (ftp_put ($ conn_id, "$ put_file", "$ dir", FTP_BINARY ))
{
Echo 123;
}
Else
{
Echo 234;
}
}
Why is the file displayed after being uploaded, but the file size is 0?
------ Solution --------------------
$ Where is put_file assigned?
------ Solution --------------------
Php file upload is not processed using $ _ POST ~ If this is correct, you need to upload the data over HTTP before FTP ~ Make sure that FTP is performed on the server.
