What is PHP in Web Development

Added 2nd May 2024


PHP, or Hypertext Preprocessor, is a widely used open-source scripting language that is especially suited for web development and can be embedded into HTML. It is a server-side scripting language used for creating dynamic web pages. Let's dive deeper into what is PHP and its role in web development.

What is PHP?

PHP is a server-side scripting language that is embedded in HTML. Hypertext Preprocessor is the recursive abbreviation for it. The HTML content created by PHP scripts is transmitted to the client's web browser after being executed on the server. As a result, dynamic and interactive websites can be made.

The Role of PHP in Web Development

Dynamic Content Generation

One of the key roles of PHP in web development is dynamic content generation. PHP allows developers to create web pages that are generated on the fly, pulling in data from databases or other sources and customizing the content based on user input or other parameters.

Form Handling

PHP is commonly used for handling form submissions on websites. It can process form data submitted by users, validate the input, and perform actions such as sending emails or updating databases based on the user's input.

Database Interaction

Another important role of PHP in web development is its ability to interact with databases. PHP can connect to databases such as MySQL, PostgreSQL, or SQLite, allowing developers to retrieve data from databases, insert new data, or update existing records.

Server-Side Scripting

PHP is a server-side scripting language, which means that the PHP code is executed on the server before the resulting HTML is sent to the client's web browser. This allows for server-side processing of data and dynamic content generation.
