Difference between PHP and JS

In the world of web development, there are two popular programming languages that reign supreme: PHP and JS. While they share some similarities, they each have their own unique strengths and weaknesses. So which one is right for you? Let’s take a closer look at the differences between PHP and JS.

What is PHP?

  • PHP is a programming language that allows web developers to create dynamic content that interacts with databases. PHP is the engine behind some of the most popular websites on the Internet, including Facebook, WordPress, and Wikipedia.
  • PHP code can be embedded into HTML code, or it can be used in conjunction with various web template systems, web content management systems, and web frameworks. PHP code is usually processed by a PHP interpreter implemented as a module in the web server or as a Common Gateway Interface (CGI) executable.
  • When PHP is used as a CGI processor, the web server software can interpret PHP code on its own and generate HTML output automatically. PHP can also be used for command-line scripting and client-side GUI applications. PHP has been widely ported and can be deployed on most web servers on almost every operating system and platform, free of charge.

What is JS?

JS is a programming language that was created in 1995 by Brendan Eich. JS is primarily used to create interactive web pages. JS code can be written directly into HTML pages or into separate JS files. JS is an interpreted language, which means that JS code is not compiled before it is run. JS runs on the client side, which means that JS code is executed by the browser. JS is a case-sensitive language. JS has a small number of reserved words. JS variables are declared with the var keyword. JS functions are declared with the function keyword.

Difference between PHP and JS

PHP and JS are two of the most popular programming languages in the world. PHP is a server-side language, while JS is a client-side language. PHP code is executed on the server, while JS code is executed on the client’s web browser. PHP is faster than JS because it doesn’t have to wait for the client to send a request before it can run. However, JS is more flexible than PHP because it can be used to create interactive web applications. PHP is better suited for back-end development, while JS is better suited for front-end development.


In the end, it’s up to you which language you choose to learn. They both have their pros and cons, and the best way to decide is to try them out for yourself. PHP has been around a little longer, so there are more resources available for learning it. However, JS is growing in popularity because of its ease of use and flexibility. Whichever language you choose, we wish you the best of luck!
