Difference Between JavaScript and PHP (with Table)

JavaScript and PHP both are two of the most versatile and mostly used scripting languages used for website development.

Many developers would agree that it’s not fair to compare one with the other as they have different purposes when it comes to website development.

While JavaScript is the most popular client-side scripting language, PHP is one of the most versatile server-side scripting languages. JavaScript deals with things on the browser side and does not need to go back to the server-side, whereas PHP handles only things at the server-side.

Anyone with a decent knowledge of C would find PHP easy to master as PHP is based on C language. While both are used widely by developers to improve the functionality of websites, they have their own share of pros and cons which definitely puts one above the other.

The difference between JavaScript and PHP is that JavaScript is used for frontend development whereas PHP is used in backend development.

What is JavaScript?

JavaScript is a high-level scripting language that synchronizes with client-side scripting. It is one of the most versatile languages of the front-end that is mainly used to make web pages interactive and dynamic. JavaScript was initially developed to perform only client-side functions, but since the release of Node.js in 2009, JavaScript has evolved to provide server-side functionalities too.

As mentioned earlier it is one of the most versatile programming languages which are specially designed to build interactive web interfaces to make websites look exceptional. It is one of the most powerful programming languages to date used to create interactive effects within web browsers even without interacting with the server-side.

In other words, it can render web pages in a dynamic way to make them look better. It brings life to web pages.

What is PHP?

PHP (short form of Hypertext Preprocessor) is an open-source scripting language that is used for server-side web development that means the scripts are only executed on the server that has PHP installed.

PHP is tasked with server-side functions such as handling request building, custom web content, etc. Nowadays, most of the websites in the world run on PHP because it is the most flexible, powerful, and user-friendly back-end content management system.

And the best part of PHP is that it can be easily integrated with a wide variety of databases such as MySQL, Microsoft SQL Server, Informix, Oracle, Sybase, etc. The thing which makes PHP so special is its simplicity and portability which thus makes it easy to master and use. It was initially designed for web development but now has evolved as a popular general-purpose language and used in a wider field.

Main Differences between JavaScript and PHP

  1. Both JavaScript and PHP are high-level scripting languages used for website development and are great for all kinds of users. However, they have different purposes. While JavaScript is a multi-paradigm high-level programming language which can be synchronized with client-side scripting, PHP is one of the most popular scripting language mostly used to perform server-side functions.
  2. JavaScript was designed to build interactive web pages and create network-specific applications without interacting with the server-side. In other words, it can make the website look exceptional just by changing the attributes of HTML tags. Whereas, PHP, on the other hand, is tasked with all the server-side functions like handling requests, building custom web content, displaying results, authenticating users, etc.
  3. While both JavaScript and PHP improve website functionality, there are some things that JavaScript does well but PHP doesn’t. However, JavaScript is a bit harder to learn because of its complexity. Whereas, PHP, on the other hand, is much more powerful than JavaScript with a bigger library and is easier to learn and use.
  4. JavaScript was built as a single-threaded functional language which is based on an event-driven model. It makes JavaScript ideal for lower-end applications such as stream servers. Whereas, PHP, on the other hand, is a multi-threaded language that can be synchronized by nature which means it will block all I/O operations to perform multiple tasks in parallel with a step-by-step approach.
  5. JavaScript has a wider use over PHP when considered in the case of a dedicated server hosting making it ideal for large-scale projects with a larger scope. PHP is a client-side scripting language that is used for a wider range of software applications.

Conclusion

The main difference between JavaScript and PHP is that JavaScript is a client-side scripting language whereas PHP is a server-side scripting language. However, since the release of Node.js, JavaScript has evolved to be used as a server-side technology hence allowing developers to build scalable network applications.

While both JavaScript and PHP have different purposes when it comes to website development, it is up to the purpose developers be using it for. PHP has a slight edge over JavaScript as it is simple and of an open-source nature, but there are things which JavaScript does that PHP doesn’t. JavaScript is an ideal tool to build network-specific applications, PHP, on the other hand, is a general-purpose scripting language used for building custom web content.
