Most PHP websites are served from systems running the popular, open-source Linux operating system. But how do we get our hands on them?

Indeed, there are a number of packages which do all the hard-work for you, and save you the hassle of installing each component PHP, MySQL and Apache individually. This package includes MySQL, a copy of the PHP programming language and the Apache web server, as well as an administrative control panel, and plugins for SSL the protocol used to encrypt traffic on a network as well as sending Email.

One has a version number of 1. Whilst I would strongly recommend that you download the latest version, the contents of this guidebook should work with both.

Linux Linux is a bit tricky. Worry no more. Read More as part of installing the WordPress blogging platform. I would recommend you to have a look at the documentation that came with your operating system.

However, there is another option.

Well, it just so happens that it comes with support for Linux, and can be downloaded here. However, where possible, I would strongly recommend that you install your LAMP server through your package manager.

There are a few reasons for this. Firstly, it would be slightly better integrated with your operating system and can be easily updated. However, the free version is more than adequate for the purposes of this guide book.

But software development? Why is that? Mainly because when you write a document, you leave all sorts of extraneous markup and formatting in the file. As a result, when writing code, we use text editors. What are they? Simply put, these allow you to write files which are saved in purest plaintext.

No formatting. Just characters. When writing code, I tend to use Sublime Text 2. It comes with an indefinite free trial although, it does occasionally nag you to upgrade , and heaps of features, which makes writing software with it a joy.

You name it, I tried it. I used each and every one of these editors for over two months as my primary day-to-day editor. Somehow, I Feeling adventurous? Hello World!

MySQL: Crash Course

Time for a whistle-stop tour of PHP. The location of your document root varies on how your PHP environment is set up. Although, depending on the PHP development package you use, can vary.

Finally, we have the content we want to print out. This is surrounded in parentheses and speech marks. If this is missing, your code will not work. However, for anything more complex, we should always aim to put it in its own PHP document.

Variables Variables are a concept found in virtually all programming languages.

They are used to store a value, which can be retrieved, used and changed later on. You might be familiar with a language that requires you to specify the value of a variable. If Statements If statements are useful.

They allow you to execute code contingent upon a specific condition being met. Consider the following code. For example: if! That is to say, that it equals 1 or less. For Loops For loops are, as a concept in programming, often quite intimidating to beginners. Functions Functions are a useful tool when it comes to programming. They allow you to write code that is more consistent, and spend less time writing the same things over and over again by compartmentalizing code into a single snippet that can be called when required.

These are known as parameters, and are put within the two parentheses in the first line of the declaration. In the next chapter, we will expand upon our understanding of the PHP programming language by looking at how we can capture data with forms, thus forming the first piece of our Twitter clone.

Forms 3. No, seriously. They are. When you leave a comment on MakeUseOf; when you download something off site and have to write down your address and credit card numbers; when you compose and submit a Tweet, you are filling out a form.

So, how do we create a rudimentary version of that in HTML? A form is enclosed within form tags.

Form takes two arguments, with the first being a link to a PHP file which contains the code that handles our form. The second is a method, and this refers to how you send data to the web server. Do you know what the difference between a TextArea and input element is? They do pretty much the same thing, although a TextArea element allows you to input multiple lines of content, whereas an Input when not used to submit a form can only accept one line of content.

This element takes a few arguments.

These can be adjusted, as you see fit. Finally, we have an input element. We should have something which looks like this.

So, remember that postForm. Create that in the document root. Now, add the following lines. In its simplest form, it means that whenever we need to reference a form input, we have to use that. This has to be sandwiched between square braces and quote marks. Simple, really. But does it work? We navigate to our homepage and write something into the form.

As you can see, our input is returned back to us. We have to put it into a database. Databases I have a confession to make. I really like databases. Everything from the password you use to log into Facebook, to the configuration of your computer, to your bank account, is stored in a database. Earlier versions of databases were fundamentally primitive and limited. Since then, they have evolved and advanced, improving the speed and reliability of their functioning. This is largely a result of 50 or so years of development.

One way of storing data is with a relational database. This paradigm of storing data was introduced in the 80s and relies upon a mesh of interconnected tables, with data organized in rows and columns. MySQL is a modern database management system. The number of websites which depend on it is dizzyingly large. It is the database behind WordPress and Facebook, and is based upon the reliable relational database paradigm. Advantages of the MySQL database are too numerous to mention.

It can be found running on every platform, having been ported to some of the most obscure operating systems in the world. This allows us to perform complex queries against a database, whilst strongly resembling written English. As a result, it is really easy for beginners to get started with.
