    Ever needed to create an FTP connection resource defaulted to a particular dir from a URI? Here's a simple function that will take a URI like ftp://username:password@subdomain.example.com/path1/path2/, and return an FTP connection resource.

    <?php
    function getFtpConnection($uri)
    {
            // Split FTP URI into:
        // $match[0] = ftp://username:password@sld.domain.tld/path1/path2/
        // $match[1] = ftp://
        // $match[2] = username
        // $match[3] = password
        // $match[4] = sld.domain.tld
        // $match[5] = /path1/path2/
            preg_match("/ftp:\/\/(.*?):(.*?)@(.*?)(\/.*)/i", $uri, $match);

            // Set up a connection
            $conn = ftp_connect($match[1] . $match[4] . $match[5]);

            // Login
            if (ftp_login($conn, $match[2], $match[3]))
        {
                // Change the dir
                ftp_chdir($conn, $match[5]);

                // Return the resource
                return $conn;
        }

            // Or retun null
            return null;
    }
    ?>
