Key Differences between PHP and JavaScript
In this ‘PHP vs JavaScript for web development’ debate, let’s now identify some key differences between both languages.
1. PHP vs Javascript: Server-side and Client-side Language
The PHP code runs on the server side not on the client’s browser, making it a server-side programming language. If a user requests a web page, PHP code is processed by the server, followed by interaction of databases, and then HTML content is generated, and sent to the client.
On the other hand, JavaScript is a client-side coding language. It means this language processes on the browser. When a web browser completes loading a web page, JavaScript improves the page’s interactivity. This enables users to submit forms, click buttons, and update content, without reloading the web pages.
2. PHP vs Javascript: Implementation
The execution of both scripting languages is different. PHP is executed on the server while JavaScript is executed in the user’s browser. The whole process works like this: when a client requests web pages, followed by the processing of PHP code on the server, after the processing of PHP script, ultimately in the form of a response to the browser.
While the execution process differs in the case of JavaScript. It is executed in the browser of the client. In this process, JavaScript code is processed by the browser, enabling the addition of animations or validation forms.
3. PHP vs Javascript: Learning Curve
PHP is quite popular as a beginner-friendly scripting language. This is due to its simple syntax and straightforward functions like managing forms, database queries, and sessions. That’s why the learning curve for PHP is normally gentle.
In contrast, JavaScript has a steeper learning curve especially for newbies. There are some difficulties you might face while working with JavaScript. These difficulties include:
- Asynchronous programming is difficult to handle for beginners.
- To ensure multiple browser combability of code.
- Advanced features like ES6 are often overwhelming for new programmers.
