ftp_chdir
Using the excellent octdec and decoct functions you can make this easy:
<?php
$mode = "644";
$mode = octdec( str_pad($mode,4,'0',STR_PAD_LEFT) );
ftp_chmod($ftp_stream, $mode, $file);
?>
ftp_chmod
(PHP 5)
ftp_chmod — FTP 経由でファイルのパーミッションを設定する
説明
int ftp_chmod
( resource $ftp_stream
, int $mode
, string $filename
)
指定したリモートファイルのパーミッションを mode に設定します。
パラメータ
- ftp_stream
-
FTP 接続のリンク ID 。
- mode
-
新しいパーミッション。8 進数 で指定します。
- filename
-
リモートファイル。
返り値
成功した場合に新しいパーミッションを、エラー時に FALSE を返します。
例
例1 ftp_chmod() の例
<?php
$file = 'public_html/index.php';
// 接続を確立する
$conn_id = ftp_connect($ftp_server);
// ユーザ名とパスワードでログインする
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// $file のパーミッションを 644 に変更する
if (ftp_chmod($conn_id, 0644, $file) !== false) {
echo "$file chmoded successfully to 644\n";
} else {
echo "could not chmod $file\n";
}
// 接続を閉じる
ftp_close($conn_id);
?>

It took me a while to figure out how to use this function in my situation because I needed the $mode to be passed to this function as a variable that was read from a database. Since the database returns the value as an integer without a leading zero, I could not get the operation to work because adding a leading zero in PHP turns the value into a string.
For example, this does not work in my situation:
<?php
// Assume that this is the value returned from the database.
$mode = 644;
// Now try to chmod using this value.
ftp_chmod($conn_id, $mode, 'test.txt');
// The file now has permissions of 204 and not 644
?>
Adding a leading zero doesn't work either:
<?php
// Assume that this is the value returned from the database.
$mode = 644;
// Now try to chmod using this value.
ftp_chmod($conn_id, '0'.$mode, 'test.txt');
// The file now has permissions of 204 and not 644
?>
I tried many ways to get it to work even converting it from oct to dec using octdec and then back to decoct and nothing worked. This is the only way I was able to get it to work, with an eval statement.
<?php
// Assume that this is the value returned from the database.
$mode = 644;
// Turn the mode into a string
$np = '0'.$mode;
// Now run chmod with the eval'd string parsed as an integer.
ftp_chmod($conn_id, eval("return({$np});"), 'test.txt');
// The file now has permissions of 644
?>
Of course, you will have to make sure that the value of $mode only contains 3 digits. Always do checking on your values before handing it off to eval().

Ok,
so if 2 people say that my way is wrong and the other is right, i will take mine back.
I posted it cause for me just the way i used it worked (i don't know why)
AND: i would not say something like: "I would try before post", in my opinion that is realy unfriendly, cause i tryed!

The "mode" parameter of the PHP5 ftp_chmod function is an integer value that is supposed to be given as an octal number, like the argument for the "chmod" command line tool.
Thus the sprintf must use the %o formatting character, so that the passed integer value is really represented as an octal number to the CHMOD site command for the FTP server.
So, IMHO, rabin's version is correct (it definitely worked for me).

rabin's code works just fine as a replacement for ftp_chmod().
I would try that before trying cspiegl's solution for pre-php 5 installations.

Hi,
The commet with the "ftp_site" is not correct!
You must use it like this:
<?php
if (!function_exists('ftp_chmod')) {
function ftp_chmod($ftp_stream, $mode, $filename)
{
return ftp_site($ftp_stream, sprintf('CHMOD %u %s', $mode, $filename));
}
}
?>

As mentioned in the note below, the function posted by "hardy add mapscene dot com" works incorrectly if used with an octal mode, the way the php5 function is used.
This function works exactly like the the php5 one:
<?php
if (!function_exists('ftp_chmod')) {
function ftp_chmod($ftp_stream, $mode, $filename)
{
return ftp_site($ftp_stream, sprintf('CHMOD %o %s', $mode, $filename));
}
}
?>
