how to include php file in html


 PHP (Hypertext Preprocessor) is a powerful server-side scripting language widely used for developing dynamic web applications. While HTML (Hypertext Markup Language) is the standard markup language for creating web pages, it lacks the ability to handle complex functionalities. In this article, we will explore the process of seamlessly integrating PHP files into HTML, enabling developers to leverage the full potential of both languages and create interactive and feature-rich web applications.

Understanding the PHP and HTML Relationship

PHP and HTML serve distinct purposes in web development. HTML is responsible for creating the structure and content of web pages, while PHP handles server-side logic and generates dynamic content. Integrating PHP files within HTML allows us to embed dynamic elements such as user input forms, database queries, and conditional statements into static HTML pages.

Setting up a Local Development Environment

Before incorporating PHP into HTML, ensure you have a local development environment set up. Install a web server (such as Apache) and PHP on your machine. Once the installation is complete, configure the server to handle PHP files. You can then proceed to create your HTML and PHP files in a designated project folder.

Using the PHP Include Statement 

The PHP include statement allows you to insert the content of one PHP file into another. By utilizing this statement, you can include the PHP file within your HTML code. To achieve this, simply place the following line of code in your HTML file, where “filename.php” is the name of the PHP file you want to include:


Copy code

<?php include ‘filename.php’; ?>

Ensure that both the HTML file and the PHP file are located in the same directory or provide the correct file path if they are in different locations.

Combining HTML and PHP Logic

Once you’ve included the PHP file in your HTML, you can combine the power of both languages. For example, you can use PHP to process form data, validate user inputs, interact with databases, and perform calculations. By embedding PHP code within HTML tags, you can dynamically generate content based on user interactions or server-side data.

Leveraging PHP’s Conditional Statements

 PHP’s conditional statements, such as “if,” “else,” and “switch,” are invaluable for controlling the flow of your web application. You can use them within your HTML to display different content based on specific conditions. This enables you to create personalized user experiences and respond to varying scenarios.

Interacting with Databases

 One of PHP’s strengths is its ability to interact with databases seamlessly. By including PHP files in your HTML, you can establish connections to databases, retrieve data, and populate HTML elements dynamically. This allows you to create dynamic pages that display information fetched from databases or provide data entry forms to update database records.

Why is my PHP code not working in HTML?

Php files can always read and display HTML code, but HTML does not automatically parse php code. To do so, you will need to make adjustments to your . htaccess file. Once that is done, the php code will display within HTML files without issue.

What is the file extension for PHP in HTML?

Normally, when PHP and HTML are combined in the same file, the file uses a . php extension and displays data in the browser. For example, this file is named hello. php.


Integrating PHP files into HTML empowers developers to create dynamic and interactive web applications. By understanding the relationship between PHP and HTML, using the include statement, combining logic, employing conditional statements, and interacting with databases, you can unlock the full potential of both languages and deliver exceptional user experiences.
