File permissions

[datona]

Simple question (I hope)

How can I get the file permission of a file and/or directory?
I am using a ftp_put function to copy a recursive directory over FTP to another server but need to preserve the file permissions.
Any help would be GREATLY appreciated.
Thanks

<?php

$ftp['host'] = 'ftp.domain.com';
$ftp['user'] = 'username';
$ftp['pass'] = 'password';
$ftp['dir'] = '/';

$ftp['conn'] = ftp_connect($ftp['host']);
ftp_login($ftp['conn'], $ftp['user'], $ftp['pass']);

$list = ftp_rawlist($ftp['conn'], $ftp['dir']);
ftp_close($ftp['conn']);

$i = 0;

foreach($list as $file)
{
	$split = preg_split("[ ]", $file, 9, PREG_SPLIT_NO_EMPTY);
	if($split[0] != "total")
	{
		$param[$i]['perms'] = $split[0];
		$param[$i]['name'] = $split[8];
	}
	echo 'File: '.$param[$i]['name'].'<br>Permissions: [ '.$param[$i]['perms'].' ]<hr>';
	$i++;
}

Thanks bpat1434 for the coding but what I am looking for is being able to read the file permissions on the source directory (local server) and then chmod on the destination directory (remote server)
Thanks for all that can help out!

well... you didn't say that in the first place.... you said from one server to the next, so I thought you were FXPing, not FTPing....

Anyway, you could always adapt it to get the permissions, and then use that to chmod the other directories.... like:

// Get the local stuff....
$ftp['host'] = 'ftp.domain.com';
$ftp['user'] = 'username';
$ftp['pass'] = 'password';
$ftp['dir'] = '/';

$ftp['conn'] = ftp_connect($ftp['host']);
ftp_login($ftp['conn'], $ftp['user'], $ftp['pass']);

$list = ftp_rawlist($ftp['conn'], $ftp['dir']);
ftp_close($ftp['conn']);

$i = 0;

foreach($list as $file)
{
    $split = preg_split("[ ]", $file, 9, PREG_SPLIT_NO_EMPTY);
    if($split[0] != "total")
    {
        $param[$split[8]]['perms'] = $split[0];
    }
    $i++;
} 

function get_level($str, $opt)
{
// This function will take the string drwxrw-r-- and convert it to an octal
    switch($str)
    {
        case 'rwx':
            $lvl = 700;
            break;
        case 'rw-':
            $lvl = 600;
            break;
        case 'r-x':
            $lvl = 500;
            break;
        case 'r--':
            $lvl = 400;
            break;
        case '-wx':
            $lvl = 300;
            break;
        case '-w-':
            $lvl = 200;
            break;
        case '--x':
            $lvl = 100;
            break;
        case '---':
            $lvl = 0;
            break;
    }
    if($opt == 'owner'){ return '0'.$lvl; }
    if($opt == 'group'){ $lvl = $lvl/10; return '0'.$lvl; }
    if($opt == 'global'){ $lvl = $lvl/100; return '0'.$lvl; }
}

function check_perms($file)
{
// This function takes the parameters we got from our local file, and grabs them from the
// array based upon the $file name.  Then, we dynamically generate the chmod octal using
// our above function
    $perm = $param[$file]['perms'];
    $perm = substr($perm, 1);
    $chmod = str_split($perm, 3);
    $i=0;
    foreach($chmod as $lvl)
    {
        if($i==0)
        {
            $chmod['owner'] = get_level($lvl[0], 'owner');
        }
        elseif($i==1)
        {
            $chmod['group'] = get_level($lvl[1], 'group');
        }
        else
        {
             $chmod['global'] = get_level($lvl[2], 'global');
        }
        $i++;
    }
    $perm = $chmod['owner']+$chmod['group']+$chmod['global'];
    return $perm;
}

// Here is where you'd connect to the other server and start your 
// modification/uploads...
// So when you call the chmod() function, you would use it like...:
chmod($file, check_perms($file));

I hope that helps you....

Thanks bpat1434
I thought as I stated that I was using "ftp_put", I just assumed people would understand.
I addapted my script to use the following code to capture the local file permission:

$perm = substr(sprintf('%o', fileperms($src_dir."/".$file)), -4);

Then I used the following to FTP the file over, then chmod the file:

$upload = ftp_put($conn_id, $installdir."/".$file, $src_dir."/".$file, FTP_BINARY); // put the files
// try to chmod $file to $perm
$chmod_cmd="CHMOD $perm ".$installdir."/".$file; 
$chmod=ftp_site($conn_id, $chmod_cmd);

Not sure if this is the streamlined method but it seems to work great.

Okay... not sure, but if it works... it works.

If anyone reads this, and wants to get my code working, here is a working example:

<?php

$f['user'] = 'username';
$f['pass'] = 'password';
$f['host'] = 'domain.com';
$f['dir'] = '/';
$files = array();
$i=0;

$f['conn'] = ftp_connect($f['host']);
if(!$f['conn']){ die('Error connecting to server!!'); }

$f['login'] = ftp_login($f['conn'], $f['user'], $f['pass']);
if(!$f['login']){ die('Error logging in!!'); }

$list = ftp_rawlist($f['conn'], "-a".' bpatterson.net'.$f['dir']);
ftp_close($f['conn']);

foreach($list as $item)
{
	$split = preg_split("[ ]", $item, 9, PREG_SPLIT_NO_EMPTY);
	if($split[0] != "total" && $split[8] != '.' && $split[8] != '..')
	{
		$params[$split[8]] = $split[0];
		array_push($files, $split[8]);
	}
	$i++;
}

function gen_octal($str, $opt)
{
	switch($str)
	{
		case 'rwx':
			$out = 700;
			break;
		case 'rw-':
			$out = 600;
			break;
		case 'r-x':
			$out = 500;
			break;
		case 'r--':
			$out = 400;
			break;
		case '-wx':
			$out = 300;
			break;
		case '-w-':
			$out = 200;
			break;
		case '--x':
			$out = 100;
			break;
		case '---':
			$out = 0;
			break;
	}

if($opt == 'owner'){ return $out; }
if($opt == 'group'){ $out = $out/10; return $out; }
if($opt == 'global'){ $out = $out/100; return $out; }
}

function get_chmod($file)
{
	global $params;
	$chmod = ''; // empty our chmod variable
	foreach($file as $fil)
	{
		$perm = $params[$fil];
		$perm = substr($perm, 1); // gets rid of whether it's a directory or not
		$perm = str_split($perm, 3);

	$lvl = '0'.(gen_octal($perm[0], 'owner')+gen_octal($perm[1], 'group')+gen_octal($perm[2], 'global'));

	echo '<strong>'.$fil.'</strong> [ <em>'.$lvl.'</em> ]<br>';
}
}

echo 'Retrieved files from '.$f['host'].$f['dir'].' successfully.<br>Checking permissions now...<br><br>';

get_chmod($files);

That gives you this type of output:

Retrieved files from *your directory* successfully.
Checking permissions now...
