Difference Between AJAX and PHP (With Table)

Due to its expanding use in practise, the term “Ajax” has become a widespread tech lingo among software developers in recent years.

For a better user experience on their websites, the majority of PHP-based sites use Ajax and jQuery-based solutions.


The main difference between AJAX and PHP is that AJAX is a set of technology to allow web – based applications to asynchronously obtain data from the server. On the other hand PHP is a programming language for creating dynamic web pages.

AJAX stands for “Asynchronous JavaScript and XML.” AJAX is a relatively new technology. for creating better, faster, and more interactive online applications by combining XML, HTML, CSS, and Java Script.

AJAX is an internet browser technology that is not dependent on the web server.

PHP (Hypertext Preprocessor) is an acronym for Hypertext Preprocessor. PHP is a server-side program designed specifically for web development.

Ajax is an open source, it can be used by anybody. It’s incredibly easy to pick up and utilise. “.php” is the extension of the files.

What is AJAX?

AJAX (Asynchronous Javascript and XML) is an acronym for Asynchronous Javascript and XML. It’s a cutting-edge method that integrates JavaScript, XML, DHTML, DOM, and Microsoft to produce clean, quick, and more dynamic web apps.

So far, AJAX has shown to be the most feasible Rich Internet Application (RIA) technology. It’s gaining a lot of traction in the business, and various toolkits and frameworks are popping up.

However, AJAX is incompatible with some browsers and is supported by JavaScript, which is difficult to manage and troubleshoot.

With Ajax, the JavaScript downloaded when the page loads takes care of most of the essential functions, such as verification and modification, as well as graphic rendering, which the Ajax engine takes care of without having to go to the server. It is transmitting received data and forth to the server at the same time as it is changing the customer’s display. However, the data transmission is not reliant on the customer’s behavior.

Google is the most well-known proponent of AJAX, having committed millions of dollars in its development.

AJAX applications can be found in many Google products, including Orkut, Gmail, Google Suggest, and Google Maps. Amazon has also created A9, its own AJAX-based search engine.

What is PHP?

Rasmus Lerdorf was a key figure in the development of PHP’s first version, as well as a contributor to subsequent versions.

PHP is a scripting language that allows you to create dynamic, interactive websites. PHP scripts, in general, run on a Web server and offer Web pages to visitors on demand. One of PHP’s most useful capabilities is the ability to embed PHP code within HTML Web pages, making it simple to produce dynamic stuff faster.

Because it’s a server-side programming language, the script generated by it will be run on the server. Apache, Nginx, and LiteSpeed are some of the server types that are frequently used with it. It’s also a free and open programming language. Users have complete freedom to customise and develop the system to meet their own requirements. Besides of Wikipedia, it’s also used by Facebook, WordPress, and a slew of other well-known websites.

One of the most fascinating facts regarding PHP is that it is used on 244 million websites. Another appealing feature is that it is free and comes with a number of templates that make website construction simple.

Even if the preceding skills of PHP do not persuade you, PHP has a few additional features. PHP is supported by almost all of today’s main servers, including Apache.

PHP supports a broad variety of databases. The most essential feature is that it is free to use and download, with anyone able to do so from the official PHP website.

Main Differences Between AJAX and PHP

  1. Ajax is a JavaScript XML that is asynchronous. It’s a collection of interconnected web technologies. PHP, on the other hand, is a hypertext processor, which is a javascript framework for producing dynamic websites that can be used for a wide range of purposes.
  2. Ajax is not a stand-alone programming language. It is a collection of technologies, whereas PHP is a single technology.
  3. PHP can operate on any platform and operating system, whereas Ajax requires a specific platform and operating system to run.
  4. On static pages, Ajax is difficult to implement, whereas PHP is simple to use.
  5. Ajax will only work if the browser supports JavaScript or XMLHttpRequest, whereas PHP does not require much support.


If you wanted to participate for a Web 2.0 or e-commerce company, or establish your own business, AJAX can be beneficial. A coder would be wise to have it in their toolkit, although it is rarely used to build an entire website! Some search engines can now read AJAX thanks to workarounds, but it’s still regarded a non-indexable computer language.

PHP is advantageous since it runs on a variety of platforms, including Windows, Unix, Linux, Mac OS X, and others. It works with a variety of databases. It works with any server that is currently in use. It is free to download and install from the official PHP website: www.php.net.
