What is PHP?

PHP is a server side programming language primarily used to create websites and web applications. It is a scripting language used in tandem with HTML, making it simple for PHP developers to create dynamic web pages. It is open source and free to use.

PHP is one of the most widely used server-side programming languages for creating websites. It is the language of choice for Wikipedia, Facebook, WordPress, and more.

Is PHP still relevant today?

PHP has been around since 1995, which is a relatively long time for web technology. However, it has gone over many changes, making the version we use today almost indistinguishable from the early versions. Nonetheless, PHP is as popular as ever. It is a secure, performant, easy-to-use, and cost-efficient way to develop a website or web application.

Web development is a fast-moving discipline, and new languages will always come and go. PHP however, has been around for a long time and is as popular as ever. It is in active development and is constantly evolving to adapt to current needs.

What does a PHP developer do?

A PHP web developer is responsible for writing the web server code that supports the front end of a web application (although a full stack developer may also be a PHP developer). PHP developers develop code to connect to a database, call a third-party API, and other web services. They support the front-end developers by giving them a way to store data and interface with other server-side technologies.

It is possible to build anything from simple contact pages to complete browser-based single-page applications that interface with client-side JavaScript to provide a rich user experience.

In addition to coding, PHP developers can also enjoy other roles:

Why should I become a PHP developer?

Being a scripting language, PHP doesn’t need to be processing or compiling before you can run it, and you don’t need any special software in order to use it. All you need is a code editor. Almost all cheap shared hosting packages already include PHP, so it’s easier and quicker than ever to get up and running.

Once you’ve learned PHP, there are many popular frameworks and applications built on top of it, such as Laravel and WordPress, that make building applications even faster and easier.

What skills do I need to learn PHP?

In addition to the language itself, a good PHP developer needs several other skills in order to be a competent developer. For example:

Here’s an example of how PHP can work with a very common use case: a contact form. In a contact form, you need to validate an email address to ensure it’s valid. There are several ways to do this in PHP, from simple validation of the format to interfacing with a third-party API to check if it actually exists.

How do I learn PHP?

You can pick up PHP rather quickly. It’s one of the easiest ways to learn software development. One of the best ways to learn it is to code with an instructor. With the PHP for Beginners course on Udemy, you’ll learn to create a simple content management system, all the time coding with the instructor.

It’s important to put what you learn into practice. As with most things, the more experience you get with something, the more comfortable you’ll be with it, and the better you’ll get as a PHP developer. PHP is so simple to start learning that you can begin coding anything you like. You could create a small personal project, then move on to more elaborate projects as your confidence increases.
