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;
}
?>
