Create folder on FTP server with PHP

Question

I use Current PHP version: 7.1.4 for Ionic2 application back-end.

I'm trying to create folder on my ftp server. With direct link to php file http://site/php/directory.php echo is

Successfully created images

After this, folder images does not exist in directory, and with second link to php, message is:

Warning: ftp_mkdir(): Can't create directory: File exists in /path/php/directory.php on line 8 Error while creating images

but folder images was not created and does not exist in directory. Then I've manually created a folder images with FTP client tool, this way folder was really created as usually.

Why with first link to http://site/php/directory.php echo was Successfully created images and with second Can't create directory: File exists in if folder images was not created, and after this, also I was able to create the folder images manually. I'm not sure, maybe it is some specific default server setting, or some kind of hidden folder. I do not have hidden files there, so no idea what is wrong here:

<?php
$ftp_server = "ftp_address";
$ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");
$login = ftp_login($ftp_conn, "ftp_username", "ftp_password");

$dir = "images";

if (ftp_mkdir($ftp_conn, $dir))
  {
  echo "Successfully created $dir";
  }
else
  {
  echo "Error while creating $dir";
  }
ftp_close($ftp_conn);
?>

The folder was created but on a different location. You have to look up where your php code is actually executed and then you will find the wrongly created folder.

From my point of view: its quite tricky to define where such a folder or file gets created. There are however "show working directory" commands which will help you out debugging this.
