Title: Build a Blog
Question: What we want to do next is to download the last blog entries, write a new entry and upload it immediately with the help of FTP.
Answer:
This lesson will introduce you to FTP and HTTP. By the way do you know whats a Blog is? Blogs are usually maintained by an individual with regular entries of commentary, descriptions of events, or other
material such as graphics or video. In the following lines were going to build a blog script.
All about the Code is a tutorial available:
