This application was created to accompany my Intro to #memtech: PHP presentation.

The purpose of the application is to show the evolution of a contrived "first" application; from a nice try with some typical, horrific mistakes to a slightly more mature application that (hopefully) demonstrates some best practices.

Versions

This project contains five "stage" branches, each representing a stage in the evolution of the app. After cloning the project, you can checkout each stage to watch the application evolve:

• stage0 - First try, with an attempt to represent some typical, first application mistakes

    git checkout -b stage0 origin/stage0
  

• stage1 - Moves duplicated code into a base file, adds error reporting

    git checkout -b stage1 origin/stage1
  

• stage1.5 - Corrects notices thrown after turning error reporting on

    git checkout -b stage1.5 origin/stage1.5
  

• stage2 - Filters input, escapes output, uses prepared statements

    git checkout -b stage2 origin/stage2
  

• stage3 - Adds a pseudo-service layer/DAO to abstract PDO calls

    git checkout -b stage3 origin/stage3
  

Usage

To use the app, clone it, check out whichever branch you want, and do the following:

• Initialize the database via php data/db/db-setup.php

If you have any permissions problems, run the following:

    chmod 777 data/db/bookshelf.db
