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.

Shopping Cart Using PHP – Learning PHP Part II

A shopping cart using php is a good place to learn how php works. I had promised to improve our simple shopping cart by adding some functionality to it. Today therefore, I have added a drop-down list to our web store so that customers can select an option describing where they found our store. It could be through television ads, phone directory, word of mouth or other sources. So, without much ado, am going to show you how our page will look like then share the php and html code.

Shopping Cart In PHP – Learn PHP Programming

A shopping cart in php will be a good example for learning. When I started using PHP, I began like most other people; the basics. I then promised to show you how to create a simple shopping cart. I have to warn you beforehand, this is not really a complex version. I figured it is smart to start with a simpler version then add more functionality to it as we proceed. So, let us get to it. I am going to do this in reverse, that is, show you snapshots of the cart then dissect the code. So, here we go!

PHP If Statements – Making Decisions PHP Tutorial

PHP If Statements can help you make decisions in code. I figured before I jump into the shopping cart, I should show you how to use if else statements which are common among many programming languages PHP included. They include if, else, and else if. I will share examples for each case and finally touch on switch statements and Arrays in this php tutorial.

PHP if Statements

[php]
#Conditional statements are used to make decisions in programs
#Here is the skeleton:
<?php
if (condition){
//do something
}else{
//do something else
}
?>
#Let me drive this point home a little easier!
<?php
if (your electric bill is due){
//go pay your bill pal
}else{
//don’t worry about it, just enjoy the light
}
?>

A really brief introduction to PHP syntax

In this php tutorial, I am going to start with some syntax then jump straight into building a simple shopping cart. Sounds exciting right? So, let us get started. Note: if you have used other languages like Java or Javascript, you will find some syntax used in PHP quite familiar. If this is your first language, do not worry, it is actually easier than you think: One more warning: The reason why I will not spend so much time teaching syntax is because there are more than enough tutorials online that do just that and I didn’t want to create yet another one!

Programming With PHP – Setting Up The Camp

After completing my first two challenges from Mozilla P2PU (HTML and Twitter API programming), I have decided to continue the amazing journey of learning new things. So what is up next for me? The answer is learning PHP. What does PHP stand for? It stands for PHP: Hypertext Preprocessor – which is a recursive acronym.

The next question you might be asking is: what the heck is PHP? I will make it simple enough to understand and then leave the rest to PHP on Wikipedia . So, php is an open-source server-side scripting language designed for web development to produce dynamic web pages. Something worth mentioning here is Rasmus Lerdorf – the creator of PHP (Give credit where it is due)!
