Reusing Code and Writing Functions – PHP

Hello! One thing you will hear everywhere you go as a coder is code reuse – the idea that if someone has already written some code that you need, you might want to consider using it instead of spending so much time writing from scratch. You could choose to repeat the process but your boss might not like it very much!

Regular Expressions – Data Validation In PHP

Hi! I am back from a serious headache and today am going to talk about regular expressions. The idea is to validate data submitted by the users of our online store. This will help us stop taking in invalid emails, or stuff like that. Also, using a new page created for feedback submission, we would like to send the message to respective departments depending on which  words our customers mention in their messages. Let us get started.

Here is my feedback page:

Putting Arrays To Work – Shopping Cart (php)

PART ONE:

Hello! Today, I want to use arrays to improve our shopping cart and find out more about them as we go a long! This post is going to be split into two: Part 1 and 2. You want read them in parts or in full. There are basically two types of arrays in PHP: numerically indexed arrays – where indices start at zero by default and non-numerically indexed arrays – where the keys can be set to whatever you deem meaningful. Let us start with numerically indexed arrays:

Storing Data Using Files in PHP – Shopping Cart

Hi! After adding some functionality to our shopping cart, I am going to do something different today: storage. Assuming we want to collect all the orders from customers and store them in a file somewhere for later use, we can easily create a file and write and read to and from it. I have altered the original look of our simple cart by adding a new input area for shipping address: Let us look at it now.

Patience, Young Padawan – More Code

Today, I am going to explore farther or deeper into what we can do with what Twitter API calls returns to us. I will make the whole post a step-by-step tutorial so that anyone interested in trying the codes out can do so with ease. So, let us get started.

[python]

#Always remember to use comments when writing code
#since we are using Python as our programming language
#of choice, we will make sure to import the necessary
#modules or libraries into our file

import urllib2
import json

[/python]

Hone Your Powers – Part 2 (JSON)

In this challenge, we are required to perform some data parsing using JSON methods. Since I am going to use Python, I will be importing some libraries into my file and then make some real API calls to Twitter instead of using the provided JSON data.

I am going to do several things and still make this post as short as possible!

[python]
#perform some data parsing using json.
#make api calls to twitter servers
#### mozilla challenge – programming with twitter api

import urllib2 #python module for handling urls
import json #json anyone??

url = ‘http://api.twitter.com/1/statuses/user_timeline/eenvincible.json’

Channel Your Vision – Call Me Maybe API

Hi! I am starting to dive deeper into the current challenge – Programming Twitter API. Just a quick basic review of the API requirements before we make any calls! Oh wait, why not take a look at what an API call looks like?

If you type the URL shown in that snapshot into your browser of choice, you will see something like this displayed:

Ugh! How messy is that? I really hope you will be able to look through that mess and identify some information that could help you build something useful!
