Web applications have become a necessity of every organization, and for creating a robust web-based application, the first step is to select a suitable programming language. PHP and JavaScript are at the top of the priority list whenever developers create a website and a web app. These languages are becoming a must-have tool in the developer’s technology stack.

When it comes to selecting only a single technology from PHP and JavaScript, it becomes a little tricky, as both are equipped with powerful modules, components, streamlines architecture, and advanced security mechanisms. In addition, each language has its advantages and drawbacks, which can be analyzed to pick the most appropriate language for a software project.

Let’s further find out about these software development technologies and compare them based on relevant KPIs, such as performance, flexibility, and security. It will help to discover the most relevant tech for web development.

An Overview to PHP and JavaScript

Before comparing these two programming languages, it is essential to have brief information. It will help you understand better, and you will select a suitable technology precisely.

What is PHP?

Personal Home Pages, Hypertext Pre-Processor, and most popular PHP are some of the names of this scripting language, which is utilized to build static and dynamic web applications. A user can easily access PHP-based solutions from the web browser to perform the required functions. In addition, it is a server-side language and can only be interpreted if PHP packages are installed on the server.

Its open-source architecture, free availability, and ample community documentation are compelling reasons for its popularity. Moreover, it has built-in functions to support the MySQL database, which aids the administrators to effortlessly configuring the backend to collect, process, and organize user data.

What is JavaScript?

JavaScript is a programming language primarily used with HTML and CSS to add behavior to web pages for enhancing their responsiveness and interaction with end-user. It is implemented on the client-side through its object-oriented programming capabilities. Moreover, its lightweight and well-grounded structure make the developers integrate it with cloud, IoT, and ML. However, it assures the production of futuristic network-oriented applications accessed over the internet.

Furthermore, it optimizes the user interface by enabling professionals to display and stream videos files, drag and drop elements, sliders, hover effects, and animations. Also, it leverages the users by terminating the page reload time whenever a new user request is executed. As a result, only a part of the web page is refreshed with new information without being noticed by the user. It helps to retain visitors to the website and enhances the conversion rate.

What is the Difference Between PHP and JavaScript?

In this section, we have discovered some of the vital key performance indicators used to differentiate between PHP and JavaScript effectively.

Basis PHP JavaScript
Server or Client Side Used for server-side scripting Used for client-side scripting
Full-Stack Utilized to create scalable backends Preferred for furnishing interactive user interfaces and flexible backends
Security More secure architecture Require third-party tools for security configuration
Web-page Interaction A highly interactive interface with animations, sliders, and gradient effects. User-friendly frontend with hover effects and minimal page reloading time
Speed Slow as compared to JS Faster than PHP in executing user-requests
Load on Network Definitive load on the server Less load on the server
Technology Support MySQL, Apache Server, MongoDB, PostgreSQL AngularJS, NodeJS, ReactJS, MySQL
Language Support Blended with HTML Embedded with HTML, CSS, XML, AJAX
Preferred App Development They are mostly considered for fabricating E-commerce websites. Reliable for dynamic Single Page Applications
Infrastructure requirement Requires a server to run and process instructions forwarded by the client device. Requires a browser, and the Command-Line interface can also run it.

PHP and JavaScript in Web Development

While comparing any two technologies being used for the same purpose, it is essential to focus on the below-listed aspects. With this comparison, you will get in-depth knowledge about the cutting-edge features of both languages and will be able to understand its need in the web development domain.

License Type

It is crucial to know about the license of the technology, as it is a vital component in determining the cost of the software project. As we compare these two technologies, PHP is an open-source development framework supported by an extensive community of experts. However, JavaScript is based on ECMAScript, making it open standard language rather than open-source.

You don’t have to pay for downloading and creating a codebase using these frameworks, but developers can only perform effective customization in embedded modules in the open-source PHP.

Availability of Resources

While designing a scalable web-based enterprise solution, hardware, software, and human resource accessibility must be cross-verified with the selected technology. There are many resources available for both PHP and JavaScript development. With the immensely emerging popularity of both these languages, more and more compatible browsers are being crafted. In addition, people are inclined to learn them both, which ensures you get the best experts affordably.

You can be assured of Full-stack development of business software through PHP and JavaScript and utilize it in the long-term due to its rapidly modernizing architecture aligned with newly introduced tech trends.

Adjoining with other technologies

Both PHP and JS are considered for producing avant-garde solutions that can be flawlessly integrated with a brand-new tech stack, such as Cloud Services, Blockchain, Artificial Intelligence, Machine Learning, and the Internet of Things. With this, the overall functioning of the web app is increased, and the expected user satisfaction rate is achieved.

Besides this, JavaScript is appraised to build IoT solutions, as it impeccably adjoins the network APIs and allows the user to configure and monitor smart devices from an appealing interface. Also, its Asynchronous code execution helps analyze each smart device’s performance and upgrade them with the latest updates simultaneously.

Compatibility with Databases

A seamless connection between the application and database is required to provide all the services smoothly. PHP is more compatible with any database because of its modules, incorporated especially for implementing MySQL databases with the solution. Whereas JavaScript requires support from NodeJS for executing server-side commands.

PHP is considered for building a reliable E-commerce store, CMS system, or any other information system due to its modernized and flexible backend development. However, JavaScript is most favored to create UIs.


Data Confidentiality and Integrity are crucial concerns, which are always analyzed while picking out any language and platform to craft a business software. The organization’s data and personal data of users is the primary asset of any company, which has to be secured at any cost.

After assessing PHP and JavaScript as per the cyber-security perspective, PHP is reviewed as a more intelligent technology, as its code is not visible in the browser. It leads to preventing Cross-site scripting attacks, which are executed mainly by modifying the code. Attackers cannot view the code, restricting them from injecting malicious components and breaching privacy. For securing the JS codebase, you need some extra tools, such as Security Analyzers, which can expand your project accounts.

Platform Adaptability

One must always choose a language that can ensure cross-platform software so that the organization can build a relationship with every user, regardless of their devices and operating system. For example, web applications developed using PHP and JavaScript are easily accessible through any browser. Nowadays, every browser comes with embedded plugins to run codes comprising JS.

In addition, PHP can also be run on any machine, as the only requirement is a browser and server configured with the appropriate service packages. PHP is also compatible with significant servers, such as Apache and IIS, leading developers to gain more control over it.


Both PHP and JavaScript are intended for fabricating web and mobile-based applications. But, JavaScript offers a great advantage of being a Full-Stack development technology. Several comparisons over the net describe JS as a frontend language, but it is unfair because it covers edge-to-edge business needs.

As contrasted with JS, PHP is only used for building dapper backends for server-side execution, which is its only drawback.
