PHP and Java Compared Side by Side

PHP and Java Compared Side by Side

The combination of PHP and Java scripts creates dynamic web pages, and many users do not see crucial differences between them. However, it is simple as it is: script written in Java is used on the users’ computers, and PHP script is used on servers. The appearance of Node.js in 2009 has changes a situation as it allowed Java to be used on a server-side, so from that moment on developers got an opportunity to select one of two languages. So what are the specifics of these languages?

PHP Peculiarities

The story of Hypertext Preprocessor started in 1995, and from that moment on it became a number one choice for developers as it serves for many purposes. Nowadays many content management systems (CMS) like WordPress or Joomla that are hugely popular among web developers use PHP so, for the most part, all sites you see on the Internet run on PHP. The reason is simple: CMS provides the easiest and the most convenient and efficient way to create a website with all major features, be it an online catalog, a blog or e-commerce website.

Java Peculiarities

JavaScript, HTML, and CSS are three fundamental tenets of the Internet and are used in almost all websites. Developers utilize JavaScript language to make web pages dynamic. Due to the development of technologies and implementation of Node.js, JavaScript is used as a server-side language.

Common features of PHP and JavaScript

Taking into consideration possibilities provided by Node.js, there are many similar features of PHP and JavaScript. Here are the most obvious ones:

  • Both languages are scripts that work in certain environments (browser and server consequently). Both are easier to use compared to other programming languages, and both are appropriate for beginners and professionals.
  • Utility type. PHP and JavaScript make up a well-known combination that is used in almost all sites: JavaScript on the browser and PHP on the server. So it’s hardly surprising that there is a vast majority of solutions, libraries, and frameworks that use both languages together.

What are the differences between these two languages?

There is an apparent response for many experts in this field: for many years JavaScript was the main script for front-end development and PHP – the most popular server-side script. However, Node.js has changed the situation completely.

  1. Different environments. Both scripts require an interpreter in the environment to fulfill their tasks. JavaScript’s interpreter is integrated into a web browser as it is impossible to imagine a browser without Java. PHP deals with this issue in such a way: developers install necessary interpreters into servers.
  2. The level of simplicity. PHP is considered to be easier than Node.js. The main difference here is a number of code lines necessary to make a server work. Both of them require a few lines of code; still, PHP requires less, and it is more understandable, it doesn’t require in-depth knowledge of closures and callback functioning.
  3. PHP enables parallel multitasking by using a block of input/output. JavaScript, on the contrary, doesn’t block input/output execution model using a single main thread of execution. However, PHP is searches and finds new ways to manage asynchronous processing.
  4. Usage of JSON (JavaScript Object Notation). Both scripts can work with JSON. However, JavaScript is more efficient with this lightweight data format.

Where are PHP and JavaScript most efficient?

Although Node.js has opened a way to a server-side for JavaScript, it is still considered to be mostly client-side script. So it is the best option for:

  • Single page apps;
  • Front-end technologies like Sybase or Backbone.js;
  • Server-side technologies like Node.js;
  • Solutions like Express.js.

PHP is best suited for:

  • CMS’s like WordPress;
  • Servers;
  • Solutions for Linux, Apache, MySQL,
