How to transfer website files between web servers using PHP and FTP
Moving website files between servers is easy and quick if you use a PHP script to FTP the files from the source server to the destination server. Downloading the website to your own computer, and then re-uploading the files to the destination web server is slow and unnecessary. Here is a PHP FTP script that helps...
I am about to transfer a Drupal installation from one PHP web server to another. It is a multisite Drupal install, with a lot of support files. In the past I have downloaded the entire file structure to my computer, and then uploaded the entire file structure to the new web server. This takes a long time. I looked around for a PHP script to make this quicker, and a great example script at uk.php.net/ftp .
I have modified the script slightly and reposted it here for convenience. I am not taking credit for any work here, the credit lies with Kristy Christie the original poster.
