3.7 Arrays

Arrays are a simple, crude but useful way of storing data for short term use in a program, for insertion into or extraction from a table or SQL file on a server. Here are the examples from the book on p46 and p47.

In the above image may be seen the folder structure on your computer when you have installed Server2Go. It includes one extra folder because I copied htdocs and renamed the old one htdocs_old. Once you’ve familiarised yourself with the opening screen I suggest you do the same and then we can start writing our own PHP files without losing the original setup.

I’ve been running a college website for what seems like forever but is in fact only 18 years and recently its free hosting failed. In the course of attempting to encourage others to reinstate it I have had to refresh my knowledge of PHP and MySQL so I thought I’d put a few notes here in case they prove useful to others in a similar position.

How far have we come in a week? You may have seen my articles and decided to try Linux Mint at no risk to your computer by using the methods I have outlined in five articles.

We’ve tried Linux Mint as a DVD boot (slow) and on a USB flashdrive (faster) there is one more method we have not tried which may suit you better. That’s running Linux Mint as a virtual machine which is closer to a real installation than either of the two Live CD options I showed you so far.


CAVEAT

This will only work if virtualisation is enabled in the BIOS of your computer and if the processor in your computer is capable of it. I am not going to attempt to cover all the possibilities of different BIOS’s and machine types here. I will start you off with this article and encourage you to do some research along these lines to establish whether or not your computer is capable of running a Virtual Machine.

Linux Multisystem iso – III

January 20th, 2016

Download the latest Multisystem iso file to your computer and burn it to a DVD using a program on your computer.

You will need a FAT32 formatted USB flashdrive minimum size 4GB. You can format it from your computer.

Boot the computer from the Multisystem DVD being sure to press F2 when the initial menu comes up and choose English at lower left then press the UP arrow key for English, followed by the Enter key, otherwise all the options will be in French. Once it’s started the screen will look something like this.

a) Move the open window to the right with the mouse by grabbing the black bar at the top.

Start your computer from the DVD we downloaded in the last post. Don’t try and log in you’ll just confuse it. Wait until it settles down to the main screen like this (click the link).

Add a wifi network connection by clicking the connect button second from left at the lower r/h corner of the screen. It looks like this:-

Or better still plug in a network cable. Now we’re ready to go.
