Downloading PHP4

I'm on a steep learning curve setting up a remote Cobalt RaQ3 Linux/Apache web server as root user. mySQL was pre-installed and I now have it up and running across telnet. I now want to download and install PHP4 and install it on the server, for which I have comprehensive instructions from WebmasterBase. Unfortunately these assume the source code has already been downloaded! My problem is how to get the source code of the php.net site and on to the server. I assume this should be done using ftp? Can someone help me with an 'idiot' guide to file transfers between the two remote machines. Incidently, I tried to access ftp://ftp.php.net from my Windows machine and couldn't get in - this may simply have been too many users? Martin --- Outgoing mail is certified Virus Free.
