Introduction 

The word "PHP" stands for "Hypertext Preprocessor". It is one of the most widely used and user-friendly open source server-side scripting languages for dynamic websites. Its first term is a personal homepage, and it was created by Rasmus Lerdorf. It is a server-side language, which means that text is executed on the server and the results are displayed in HTML in the web browser.

PHP is one of the few scripting languages that has no problem connecting to databases such as Oracle, MySQL, Sybase, PostgreSQL and Microsoft SQL Server, to name a few. PHP 7.4 is the latest version of the language. It is one of the most powerful languages when it is easy to learn. PHP is used to run some popular websites including Yahoo.com and Facebook.com. There are many reasons for this popularity, but one of the biggest is the ability to embed it in HTML files. HTML code can be embedded in PHP files. HTML is a client-side language, so it differs from PHP in some ways.

As mentioned earlier, PHP code execution takes place on the server, while HTML code execution takes place on the browser itself. Only the client has access to the information provided in the output form of the PHP script. They don't know the original PHP file stored on the server and loaded the code. PHP is compatible with JavaScript, CSS, and other client languages besides HTML. 

Advantages of PHP

You will know the difference if you work with PHP, Java or other languages. Here are some features that make PHP special: 

Open Source: This project is managed by developers worldwide. It is possible to download and use the source code for free.

Easy to learn: If you are a beginner or just entering the world of programming, PHP is the language you should start with. Functionality: PHP can be a very functional language, depending on the type of web developer programming. When you write code, it is flexible and can be used to create a large number of applications. When a website consists of many web pages, it is the programming language of choice.

Flexibility: PHP is highly flexible, whether it's in the middle of a project or after it's done. Since performance can change at any time during the operation, the flexibility of the written language is important. The best thing about PHP is that it lets you make changes even after you start the project, which saves you time. There is no need for the developer to write new command code or functions as it can be done and use updates to existing code.

Community: PHP documentation and support is easy to find because it is a global community supported by developers.

Let's find out what PHP developers do and how much they earn now knowing what PHP is, how it works, and how it differs from other server side scripting languages.
