A few focused tips that build on what , and said: the two common causes for "mkdir works locally but not on the host" are (1) the path is wrong for that host and (2) the webserver/user lacks permission or the host restricts filesystem access. Since later reported it worked, it may have been a transient host-side issue — but the snippet below is a safer, repeatable approach for production.

// create an uploads folder next to this script, but do it safely
$dir = __DIR__ . '/uploads';

if (!is_dir($dir)) {
    if (!mkdir($dir, 0755, true)) {
        $err = error_get_last();
        error_log('mkdir failed: ' . json_encode($err));
        // handle failure (show friendly error / contact host)
    } else {
        chmod($dir, 0755); // adjust only if needed
    }
}

if (!is_writable($dir)) {
    error_log('Upload dir not writable: ' . $dir);
    // fallback / notify admin
}

Use absolute paths built from __DIR__ or $_SERVER['DOCUMENT_ROOT'] rather than guessing /htdocs/...; check existence with is_dir() and writability with is_writable() before creating or uploading, and catch failures with error_get_last() so you can log the precise warning. (php.net)

Security & troubleshooting notes: avoid making folders world-writable (0777) unless you understand the risks; prefer 0755 or 0750 and use server-side file validation. If PHP cannot create folders despite correct paths and perms, hosts sometimes enforce restrictions (open_basedir, chroot, or other limits) — check error logs or contact the host. (php.net)

You may also need to deal with permission issues. The web server typically runs as a different user (such as "nobody") than the user you use to manually create files/directories via FTP or command line.

If you create a directory with your PHP script, the owner will probably be the web server user and not you. So in addition to reading about the mkdir() function, you might also want to read about chmod() to set permissions accordingly.

Well from that path specified, if it were on an online server it would look like if you have a dedicated server or same server configurations as your testing environment. When placing a / at the beginning of the path, it makes the location start from the beginning of the server root and usually there are a few folders it has to go through before getting to your account. I would suggest making a relative path to the script so for example, if the script was in your hompage or the same directory as your homepage then the following would apply:

<?php
  mkdir ("lucky", 0777);
  echo " dir made successfully";
  ?>
