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;
}
?>
