On this site, we've previously discussed several web languages, such as HTML and CSS layout, as well as several JavaScript samples. Today, I'd like to present you with a fourth case, which has surfaced on prior occasions but has not yet been thoroughly examined by our team. It has everything to do with PHP. There are some differences between this language and its predecessors. It is distinct in that it cannot be processed directly within the browser without requiring external resources. We must first enable the system to comprehend it by installing a software package, which we shall cover in more detail later.

What advantages does PHP provide, and why should we employ it?

PHP is a programming language used to handle data on servers and display it mostly on screens. In practice, we will see it in action whenever it is essential to obtain information from a database to perform tasks such as user management or product listing. Form registrations (made in HTML) and online businesses where gender is displayed in tables are examples of this application type. But how does it function? To answer that question, we must first keep in mind that we require a system that is capable of executing the code in question, and of doing so, it must install the following software:

MySQL is a database management system that is powered by Apache, a web server software package. Works with the SQL protocol, a standard for organising data on a server, and PHP, which is the programming language we wish to use as our target.

The WAMP package (also known as MAMP or LAMP depending on whether you are using Mac or Linux) is used to set up the entire environment for us to operate to have this three software available. This is when we discover that PHP is becoming more sophisticated in terms of infrastructure than in the previous instances. Still, the most intriguing thing about it is that HTML, CSS, JavaScript and PHP can all be used together and are very tightly related to one another. I'll give you a situational example to help you better grasp what I'm talking about: let's say we want to add a new user to our system. Need:

A form, which it will create in HTML.

It will use Styles to make it more visually appealing, which will be accomplished using CSS.

A piece of computer code that will logically log into a database is required. This is where the PHP programming language comes in.

The next step and which is optional is to utilise JavaScript to interact with the user in the form of "Registered User" type messages, which will show on the computer screen.

Now that we understand what we require and how they interact, we can consider what role PHP plays in the process. To make queries to the server, we must first understand SQL (instructions that allow us to know the amount of data we have or even make filters under some parameters). Consider the following scenario: we want to view just the glasses at an online store that sells home supplies for the kitchen. If we didn't use PHP and instead used HTML, we'd have to create all of the tables one by one, product-by-product, which means that if a new glass is added to our inventory, we'd have to go back to HTML and manually input it. When using PHP, what occurs is that the server is "asked" for the number of cups there are. A loop (similar to the one we use in JavaScript) is used to generate a table that is automatically, or as it is known in programming, "dynamically." Since there are new goods in the database, we don't have to manually update the table, which saves us a great deal of time and effort. In the opposite situation, the same thing occurs: PHP will make the necessary changes for us if a piece of data is destroyed.

Now that we understand how PHP works and what it is used for let's look at how we may learn it.

WAMP will be required to get things started, as I've already said (or the version for our operating system). Once the software is installed, we may begin creating files in the ".php" format. I propose that you visit the W3Schools online academy, where you can get step-by-step instruction on basic principles, as well as examples that you can put to the test in real-time. I hope this helps. We will use the following syntax to indicate that we will be writing PHP code:

php? php? php?

code

?>

Take note that it is quite similar to the code that we use to begin JavaScript code, which is:

<script>

It must assume that everything you learnt in JavaScript, such as loops, variable assignments, and so on, is present here. For example, if defining a variable in JS is accomplished by the following:

var is the value of the variable.

In PHP, we would write:

variable = value of variable in $ variable

Once again, we are reminded of what I noted previously: if we master one programming language in-depth, the others are simply variations on the same principles in a different language. This means that, even though the code is written differently, the concepts of declaring variables, creating loops, producing conditions, and so on remain the same.

After doing a little summarising, we have the following:

1. PHP is used to create dynamic websites, which is very useful when dealing with data that changes over time.

2. When used in conjunction with HTML, CSS, and, if applicable, JavaScript

3. It is a language that necessitates the installation of the WAMP software (MAMP or LAMP according to Mac or Linux)

4. It has the potential to save us time by displaying data to consumers.

5. Because it is a web language, we do not require a large machine to learn it.

W3Schools, in particular, has a large online community from which we may learn a great deal.

I strongly advise you to learn, and you can do it by signing up for our Programming with HTML5 and CSS course, which includes the PHP module. There you will discover all of the information you need to complete this schedule without difficulty and with the assistance of a teacher.

We live in an era in which the network is critical, and more and more businesses are requesting developers who are familiar with this programming language to take advantage of the many advantages it provides for online stores, pages with various data that they wish to display to their users, and other applications.
