Subject: Tips on programming (in PHP)
Hi,
Some suggestions for new php programmers (newbies).
DO NOT treat company websites like personal websites. They have more than
just a blog, three four static pages and a contact form. Ofcourse many of
the sites have onlythese, but I am talking about "PHP applications" which
are database and task oriented.
Develop the application in some standard. If you don't know any standard,
do some research on google. Follow consistent variable namings and write
comments on what the code block will do. Validate all inputs and before
sending the data to databases, properly escape the strings.
SQL injection is the biggest attack. Know about it. Send least important
data in cookies and place everything else in Sessions or in database, but
not in text files, because they will be accessible through a browser.
After developing your application, give it to your competitors to crack
your site. If they are successful, you have to learn how to avoid the
attacks. If they fail, go and have a party. It is all set.
Documentation is a crucial thing in PHP applications or websites developed
for companies. There will be another person maintaining the site developed
by you and he SHOULD understand what the site is. Three kinds of basic
documents are needed.
1. Requirements document: Which says why they need a website. and what is
expected out of the site. No technical stuff here.
2. Prototype document: The document explaining the site functionally, It
is a rough layout with dummy data plus some reasons why the content is
placed on particular page.
3. Coding document: Completely technical. A list of classes, their
properties or methods, etc. Functions or frameworks used. Database tables
and their descriptions etc.
While preparing a manual include as many screenshots as possible by naming
them sequentially, because a picture is worth a hundred words.
I strongly recommend reading "PROFESSIONAL PHP" book by Wrox Publications
