Debugging With Eclipse and PHPdbg in Linux

Submitted by Paulus on Mon, 05/21/2007 - 01:23
Using a debugger to help find errors will save you a consider amount of time. Eclipse is a great IDE because not only is it platform independent, but you can use it to program in many different languages. The features and plugins seem endless which is an added bonus. The main reason why I like it is that it works on Linux. ;)

Prerequisits

  • PHP 5
  • Apache
  • PHPdbg
  • MySQL or some other DB (if you are planning to use a database)

Installation

I am running Gentoo Linux in 64-bit mode, so a lot of packages are masked.

Views

Views have two purposes:
  • Simplify issuing complex SQL queries
  • Restrict users' access to sensitive data.
Views are Database objects and are treated like tables. Unlike tables, views do not store any data.

IVMan Automounter in Gentoo

Introduction

Linux is great in the respect that you have COMPLETE control over everything you do on the system. You can even control the mounting of drives. However, sometimes you may just want the system to mount it itself. I've read that many people were having problems with supermount and it is no longer mainstream. This is where IVMan comes into play. Submount was removed from the Gentoo Portage as of 2nd of Janurary, 2007.

Rearming Windows Vista

Introduction

At work we have a Core 2 demo running Windows Vista. This demo is not connected to the network because we don't want people coming in and changing the background image to display something obscene or pornographic. There is a neat little trick that I found one day while trying to figure out how I could reset the time until the user had to activate Windows Vista.

What to Do

When you log into Windows and your grace period has expired, you can still use Windows with reduced functionality. In reduced functionality mode, you are still able to use IE7.

Subqueries and Merges

HTML Source EditorWord wrap Sub queries come in handy when you want to find a record but need to know what exactly to look for. For example, if you want to find all the items that are more expensive than a specific item. Instead of issuing two SELECT statements, you can use sub queries to find the answer in just one query.

Restricting Selects and Sorting Data

When you select data, there’s a good chance that you’re looking for something specific. In using the SELECT statement you can attach a WHERE clause to limit the data that you are looking through. If you’re very good and know what you’re looking for then you can use the WHERE clause to find exactly what you want.

Joining Tables

Joining tables brings together data from two or more tables in one query in order to get all the information you need. There are six different types of joins:
