Know What PHP is Used For in Web Development?

PHP is one of the important coding languages in the dynamically competitive world of web development. It plays a pivotal role as a server-side scripting language to build an engaging and captivating website; PHP has always been a silent but impactful architect, shaping our digital initiatives. 

This article is designed to take you through the important aspects of PHP, unveiling its significance and growth journey over time and spotlighting its indispensable role in web development.

Overview of PHP

PHP was initially introduced in the web development world as a “Personal Home Page” and has evolved into a “Hypertext Preprocessor.” Unlike replacing HTML, it works alongside it. 

In the mid-1990s, Rasmus Lerdorf created PHP to keep track of people visiting his online resume. Back then, it was pretty basic. However, as time passed, PHP improved, and by 1998, PHP 3 was developed with improved features. Now, it has become a super popular scripting language for building websites.

PHP as a Server-side Scripting Language

PHP stands out in web development because it operates behind the scenes on the server. When you interact with a PHP-based website, such as clicking a button, the server handles the code execution, performs necessary tasks, and displays the outcomes. 

This ensures that users enjoy a customized and interactive experience without being exposed to the technical complexities in the background.

How PHP Works in Web Development?

PHP works as a valuable server-side scripting language in web development. It plays an important role in processing and executing tasks on the server before delivering the final output to users. The typical workflow involves the following steps:

1. Client Request

• A user initiates a request by accessing a PHP-based web page through a browser.
• The request is sent to the web server hosting the PHP files.

2. Server-Side Processing

• PHP code embedded in the requested web page is executed on the server.
• This server-side processing generates dynamic content, interacts with databases, and performs various computations.

3. Output to Browser

• After processing, the content, often HTML, is sent back to your web browser.
• Your browser then understands and shows you the result.

4. Dynamic Interaction

• PHP enables dynamic interactions by allowing users to submit forms, input data, or trigger events.
• The server processes these interactions, updating content dynamically without requiring a full page reload.
