Clearing file contents

Hi,

Thanks for the reply...

But, as I mentioned earlier if the filesize is very large, say 500MB, then if I use the command ">filename", it will clear the file contents, but, when I do the "ls -l filename" it will will show the file size as 500MB itself, not as 0 bytes.

If the filesize is less, it will work without any problem.

It will be of great help, to get any other UNIX command which will clear the file contents.

Regards,
Raghu

ftp_alloc - Allocates space for a file to be uploaded

SYNOPSIS
bool ftp_alloc (resource $ftp_stream, int $filesize, [string &$result]) DESCRIPTION
Sends an ALLO command to the remote FTP server to allocate space for a file to be uploaded. Note Many FTP servers do not support this command. These servers may return a failure code ( FALSE) indicating the command is not sup- ported or a success code ( TRUE) to indicate that pre-allocation is not necessary and the client should continue as though the oper- ation were successful. Because of this, it may be best to reserve this function for servers which explicitly require preallocation. PARAMETERS
o $ftp_stream - The link identifier of the FTP connection. o $filesize - The number of bytes to allocate. o $result - A textual representation of the servers response will be returned by reference in $result if a variable is provided. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 ftp_alloc(3) example <?php $file = "/home/user/myfile"; // connect to the server $conn_id = ftp_connect('ftp.example.com'); $login_result = ftp_login($conn_id, 'anonymous', 'user@example.com'); if (ftp_alloc($conn_id, filesize($file), $result)) { echo "Space successfully allocated on server. Sending $file. "; ftp_put($conn_id, '/incomming/myfile', $file, FTP_BINARY); } else { echo "Unable to allocate space on server. Server said: $result "; } ftp_close($conn_id); ?> SEE ALSO
