PHP is a server-side programming language that has been around for more than 25 years. Developers today tend to have strong feelings about it. When a new programming language or tool comes out, people will probably talk about where PHP is "dead." The Stack Overflow annual developer survey shows that PHP has moved down the list of the most popular programming languages, from fifth in 2017 to eighth in 2020. Even so, PHP is still used by nearly 80% of all websites. For example, WordPress and Facebook both run on PHP. So what's up?
Why is PHP still used by so many people?
PHP, or Hypertext Preprocessor, is a scripting language that can be used for many different things. It can be used to make dynamic and interactive websites. It was one of the first server-side languages that could be embedded into HTML. This made it easier to add functionality to web pages without having to call external files for data. Its use has changed over time, as new versions (version 8.0 came out in November 2020) have added features and unlocked new ones.
Even though PHP isn't the sexiest language these days, here are some of its best features that show why it's still so important in web development.
It's easy to learn and use: One of the main reasons PHP became so popular is that it's easy to get started with. Most people could make a web page with just one PHP file in a short amount of time, even if they didn't know much about web development or had a lot of experience with it. PHP is easier to learn than many other languages because the syntax is easy to understand and the command functions are simple.
It's free because it's open source: This also makes it easier for developers to start using PHP because it can be set up quickly and for free. A lot of PHP frameworks, like Laravel and Symfony, are also free to use. Companies also like this feature because it helps keep the costs of building a website in check.

It can be used in many different ways: One of the best things about PHP is that it can be used on Mac OS, Windows, Linux, and most web browsers. It also works with all the major web servers, which makes it easy to use on different systems and platforms with little extra cost.
It has a lot of support from the community: PHP is a scripting language that has been around for a long time and is widely used. It now has a large and loyal community of people who support it. There are a lot of tutorials, Frequently Asked Questions (FAQs), and tips to help new PHP developers get started and to keep pushing the limits of what the language can do with regular updates.
It's quick and safe: Every company wants its website or app to be fast and safe. PHP has its own memory and can keep up with other languages in terms of speed, especially when using newer versions. People have asked about PHP's security in the past, but it's important to remember that it's not inherently more or less secure than other programming languages. Because it is used a lot and has a lot of community support, there are now a lot of tools, frameworks, and best practices that can help fix weaknesses and protect against cyberattacks.
It works well with databases: PHP makes it easy to connect securely to almost any kind of database. This gives developers more freedom to choose the database that works best with the app they are making.
It's been tried and true: The fact that PHP has been around for 25 years means that its code has been tested in many different real-world situations. The main bugs have been found and fixed, which makes the language more stable and gives developers more confidence in it. Also, over time, many frameworks and tools have been built that make PHP web development safer, more efficient, and more effective.
There is a lot of code from the past: Okay, this isn't really a benefit of PHP by itself, but when so many websites are already written in PHP, it becomes an important thing to think about. Simply put, it is usually easier to make changes in the same language than to try to rewrite everything in another. This helps PHP stick around even if some younger developers would rather use a different language. Because PHP has been around for a long time, it is also usually easier to find a PHP developer for your business. However, as we have said before on this blog, you should make sure they have the right skills.
