ftp_size -- Returns the size of the given file


int ftp_size ( resource ftp_stream, string remote_file)

ftp_size() returns the size of a remote_file in bytes. If an error occurs, or if the given file does not exist, or is a directory, -1 is returned. Not all servers support this feature.

Returns the file size on success, or -1 on error.

Example 1. ftp_size() example


$file = 'somefile.txt';

// connect to the server
$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

$res = ftp_size($conn_id, $file);

if ($res != -1) {
    echo "size of $file is $res bytes";
} else {
    echo "couldn't get the size";

This will return the filesize on remote host and the size if you download it in FTP_BINARY mode. If you are using FTP_ASCII in ftp_get() the size can be changed.

$file= 'filename with space.txt';
$size = ftp_size($this->ftp, urldecode($file) );

this one can correctly return the size
otherwize, it always return -1
