ftp_size — Gibt die Größe der angegebenen Datei zurück
ftp_size() gibt die Größe der angegebenen Datei in Bytes zurück.
Hinweis:
Nicht alle Server unterstützen dieses Feature.
Der Verbindungshandler der FTP-Verbindung.
Die entfernte Datei.
Gibt bei Erfolg die Dateigröße zurück, sonst -1.
Beispiel #1 ftp_size() example
<?php
$file = 'somefile.txt';
// Verbindung aufbauen
$conn_id = ftp_connect($ftp_server);
// Login mit Benutzername und Passwort
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// Ermitteln der Größe von $file
$res = ftp_size($conn_id, $file);
if ($res != -1) {
echo "$file ist $res Bytes groß";
} else {
echo "Größe konnte nicht bestimmt werden";
}
// Verbindung schließen
ftp_close($conn_id);
?>
To overcome the 2GB file size limit, you can open your own socket to get the file size of a large file. Quick and dirty script:
<?php
$socket=fsockopen($hostName, 21);
$t=fgets($socket, 128);
fwrite($socket, "USER $myLogin\r\n");
$t=fgets($socket, 128);
fwrite($socket, "PASS $myPass\r\n");
$t=fgets($socket, 128);
fwrite($socket, "SIZE $fileName\r\n");
$t=fgets($socket, 128);
$fileSize=floatval(str_replace("213 ","",$t));
echo $fileSize;
fwrite($socket, "QUIT\r\n");
fclose($socket);
?>

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, $file_name));
So you can get the real size of big files. But this method is not good for checking is this a dir (when ftp_size() returns -1).
For checking if a certain folder exists try using ftp_nlist() function to get a directory list in array. By using in_array('foldername') you can find out if it is there or not.
note that project_t4 at hotmail dot com's example above doesn't work in general, though it works on his Win2K/Apache server; as far as I can tell there is no way to check over ftp whether a directory exists. This function's behavior given a directory name seems to be at least somewhat dependent on your OS, web server, or ftp server, I don't know which.
Well this function is nice but if you have files larger then 2.1Gb or 2.1 Billion Bytes you cannot get its size.
To get a dirsize recursive you can use this simple function:
<?php # copyright by fackelkind | codeMaster
function getRecDirSize ($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, "/");
?>
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, $item) == "0")
{
echo "<br>Directory:: ".$item;
} else {
echo "<br>File:: ".$item;
}
}
This outputs a list of the remote directory and indicates which items are directories and which are files.
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
