ftp_size

Returns the size of the given file (PHP 4, PHP 5)
int ftp_size ( resource ftp_stream, string remote_file )

Example 749. ftp_size() example

<?php


$file = 'somefile.txt';

// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// get the size of $file
$res = ftp_size($conn_id, $file);


if ($res != -1) {

    echo "size of $file is $res bytes";

} else {

    echo "couldn't get the size";

}

// close the connection
ftp_close($conn_id);

?>

Well this function is nice but if you have files larger then 2.1Gb or 2.1 Billion Bytes you cannot get its size.

To get a dirsize recursive you can use this simple function: <?php # copyright by fackelkind | codeMaster function getRecDirSize ($connection, $dir){ $temp = ftp_rawlist ($connection, "-alR $dir"); foreach ($temp as $file){ if (ereg ("([-d][rwxst-]+).* ([0-9]) ([a-zA-Z0-9]+).* ([a-zA-Z0-9]+).* ([0-9]*) ([a-zA-Z]+[0-9: ]*[0-9]) ([0-9]{2}:[0-9]{2}) (.+)", $file, $regs)){ $isdir = (substr ($regs[1],0,1) == "d"); if (!$isdir) $size += $regs[5]; } } return $size; } $dirSize = getRecDirSize ($conID, "/"); ?>

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.

note that project_t4 at hotmail dot com's example above doesn't work in general, though it works on his Win2K/Apache server; as far as I can tell there is no way to check over ftp whether a directory exists. This function's behavior given a directory name seems to be at least somewhat dependent on your OS, web server, or ftp server, I don't know which.

Just to let people out there know, on my windows 2000 server running Apache and php i was returned 0 not -1 for directories. foreach ($dir_list as $item) { if(ftp_size($conn_id, $item) == "0") { echo " Directory:: ".$item; } else { echo " File:: ".$item; } } This outputs a list of the remote directory and indicates which items are directories and which are files.

For checking if a certain folder exists try using ftp_nlist() function to get a directory list in array. By using in_array('foldername') you can find out if it is there or not.

2 adams[AT]techweavers[DOT]net: To get a size of large file (f. ex.: 3.2 Gb) you have to format the result returned by ftp_size(): $size = sprintf ("%u", ftp_size($connection, $file_name)); So you can get the real size of big files. But this method is not good for checking is this a dir (when ftp_size() returns -1).

$file= 'filename with space.txt'; $size = ftp_size($this->ftp, urldecode($file) ); this one can correctly return the size otherwize, it always return -1
