How to obtain chmod information via FTP

I am currently working on an online FTP client that would work similar to a normal FTP client found on a desktop. I am currently having trouble obtaining chmod permissions over FTP.

I have tried the fileperms() function in PHP, but it does not allow the FTP protocol, only intended to be used for local files on the server you are accessing.

If you are using PHP 7.2 and newer and your FTP server supports MLSD command, it's easy, as you can use ftp_mlsd function.

$conn_id = ftp_connect("ftp.example.com") or die("Cannot connect");
ftp_login($conn_id, "username", "password") or die("Cannot login");
ftp_pasv($conn_id, true) or die("Cannot change to passive mode");

$entries = ftp_mlsd($conn_id, "/remote/path") or die("Cannot list directory");

foreach ($entries as $entry)
{
    if (($entry["type"] != "cdir") && ($entry["type"] != "pdir"))
    {
        echo $entry["name"] . " - " . $entry["UNIX.mode"] . "\n";
    }
}

If not, you have to use LIST command using ftp_rawlist function and parse a proprietary format that the server returns.

The following code assumes a common *nix format.

$entries = ftp_rawlist($conn_id, "/remote/path") or die("Cannot list directory");

foreach ($entries as $entry)
{
    $tokens = explode(" ", $entry);
    $name = $tokens[count($tokens) - 1];
    $permissions = $tokens[0];
    echo $name . " - " . $permissions . "\n";
}
