What is the meaning of PHP and where it is used

Have you ever wondered how Facebook was created? It’s all thanks to a powerful programming language called PHP, which stands for “Hypertext Preprocessor”. This is a server-side scripting language that is not only open-source, but also a general-purpose programming language.

It is mainly used for web development and can be embedded with HTML to add new features. Its main strength lies in its ability to design dynamic websites. When a user sends a request to a PHP web page from their browser, the PHP code is processed within the PHP module installed in the web server. This generates HTML output which can be viewed in your web browser.

To better understand how PHP works, let’s first explore some of the technical terms used in the previous paragraph. There are different types of web pages out there, and Its works on dynamic web pages. This means that the content of the page changes based on the user’s request or other input. With it, you can create websites that are more interactive and engaging for your audience.

Programming Language

Programming languages are like the dialects we speak in our everyday life, but the catch is that these are the languages that the computers can comprehend. These computer programming languages serve as a medium of communication between humans and machines. They are utilized to develop a plethora of software applications and websites.

Some popular programming languages are BASIC, C, C++, Java, COBOL, FORTRAN, PHP, and HTML. They are each unique in their own way and are used for various purposes. Programs are written in these languages only and are then executed by the computer. So, it’s like teaching your computer to understand your commands and perform the desired actions. Pretty cool, isn’t it?

General Purpose Programming Language

Imagine that computer programming languages are like different languages that people use to communicate with each other. Just as we use English, Spanish, French or Mandarin, computer programmers use programming languages like BASIC, C, C++, Java, COBOL, FORTRAN, PHP, HTML, etc. to communicate with computers and create various types of software.

Each programming language has its own specific uses, just as each human language has its own unique features and characteristics. For example, if you want to create a calculator software, you might use Java or C++, but if you want to make a website, you would use PHP or HTML. These languages are called Domain Specific Languages because they are designed for specific purposes or domains.

Scripting Language

Did you know that there are two main types of programming languages – compiled and interpreted? And, one of the interpreted languages is scripting languages. These languages are different from compiled languages in the sense that they don’t need to be compiled before running. Instead, they have a set of instructions, called scripts, which are interpreted by the computer to perform the desired task.

Languages like PHP, Perl, and Python are examples of scripting languages. These languages are often used for web development, as they can be executed in a web browser or web server without the need for compilation.

Static Web Page

Have you ever come across a website where all the pages remain the same for everyone, regardless of who the user is? Well, these types of web pages are called static web pages. The content on these pages is fixed and cannot be changed by a normal user. When you open such a website, you will see the same content every time, which is the same for every user.

Examples of static web pages are “About Us” and “Contact” pages, where the content remains the same for everyone. But, have you noticed that some websites like Facebook.com have different web pages for different users, and the content keeps changing all the time?

This type of web page is called a dynamic web page. When a user requests a dynamic web page, the content is generated dynamically based on the user’s input or interaction with the website. And this is where PHP comes into the picture. PHP is widely used to create dynamic web pages because it allows the creation of interactive and personalized web pages that respond to user input.

Dynamic Web Page

Dynamic web pages are like chameleons, always adapting and changing based on the user’s needs and preferences. When you open a dynamic webpage, the content displayed to you is unique and personalized. For instance, when you log in to your Facebook account, the page that appears is tailored to your preferences and interests, and is different from what someone else sees on their account.

Similarly, on online shopping websites, the pages keep changing based on the user’s search history and preferences. These ever-changing web pages are examples of dynamic web pages.

If you want to create your website and have the freedom to design it according to your taste, then you must learn PHP. With PHP, you can create dynamic web pages that can change their content as per the user’s input. So, buckle up and get ready to unleash your creativity with PHP!

How and where to learn PHP

Designing your own website or building one for your business or clients can be an exciting venture. However, many people are held back by their lack of knowledge and skills in this area. While there are many web developers out there who can help you create your website, their services can come at a high cost ranging from 30,000 to 200,000 or even more.

But don’t be disheartened! Learning PHP can be a great way to create your own website and even earn some income by designing websites for others. The best part is that you don’t need to invest a lot of time and resources to learn PHP.

There are many online resources, tutorials and courses available that can help you learn PHP at your own pace. With some dedication and practice, you can master this language in just a few weeks or months.

Now let’s talk about the history of PHP.

History of PHP Language

It was first created by Rasmus Lerdorf in 1994, with a simple goal to maintain his personal website. Initially, it was just a set of Common Gateway Interface (CGI) scripts written in C language. However, over time, it evolved and got released as a scripting language for web development in 1995. The name “PHP” originally stood for “Personal Home Page,” but now it stands for “Hypertext Preprocessor.” Today, it is one of the most popular programming languages used for web development.

Let me tell you an interesting story about PHP – a WEB-BASED PROGRAMMING LANGUAGE that came into existence in 1995. Its creator was Rasmus Lerdorf who initially wrote a program called Common Gateway Interface (CGI) using the C programming language. He used this program to create his personal homepage, but his interest in databases led him to create a web page using his database. It was then that the name of this language was coined as PERSONAL HomePage/Form Interpreter or PHP/IF.

This language was specifically designed to create dynamic web pages. Over time, a tool was developed to make this language even better, known as Home page tool 1.0. By 2013, many new features were added to PHP and it became a popular language for web development. The ability to embed PHP into HTML made it easier to create interactive websites. As a result, it started being used to create some of the world’s biggest websites.

PHP language creators and contributors

It was created by Danish-Canadian programmer Rasmus Lerdorf in 1994. He initially created PHP as a set of Common Gateway Interface (CGI) scripts to track visitors to his personal website. Over time, Lerdorf added more functionality to it and released it as open-source software.

In 1997, two developers named Andi Gutmans and Zeev Suraski rewrote it’s parser, creating PHP version 3, which significantly improved the language’s performance and expanded its capabilities. Gutmans and Suraski went on to found Zend Technologies, a company that would become a major contributor to it’s development and support.
