In this article, we’ll look at how to use PHP in HTML. Some of the approaches for integrating PHP and HTML are covered here.

PHP tags can be added to your HTML page. Simply surround the PHP code with the PHP starts tag?php and the PHP end tag?>. PHP code is enclosed between these two tags, and it will be executed on the server before the requested file is provided to the client browser.

To utilize PHP in HTML, use the.php extension because PHP code is interpreted and executed on the server side.

Using PHP in HTML allows developers to embed dynamic content within a webpage. If you’re new to this concept, here’s a quick introduction:

  1. File Extension: For the PHP code to be executed, the file extension should be .php. Although the file has a .php extension, it can contain both HTML and PHP code.
  2. PHP Tags: PHP code is embedded within the PHP opening <?php and closing ?> tags.
Steps to Use PHP in HTML
  • Setting Up a Local Server:

Before you can execute PHP code, you need a web server. One of the popular choices for beginners is XAMPP. Download and install it from the official website.

  • Creating a .php File: 

Use a code editor (like Visual Studio Code, Atom, or Sublime Text) to create a new file. Save it with a .php extension, for example, index.php.

  • Embedding PHP in HTML:

In index.php, you can mix HTML and PHP like this:

<!DOCTYPE html>



    <title>PHP in HTML</title>



<h1>Welcome to my website</h1>


    echo “<p>This content is generated by PHP!</p>”;


<p>This is regular HTML content.</p>



  • Running the File
  • Move the index.php file to the ht docs directory of your XAMPP installation (typically C:\xampp\htdocs on Windows).
  • Start the Apache server using the XAMPP control panel.
  • Open a browser and navigate to http://localhost/index.php.

You should see the HTML content with the PHP-generated content integrated.

Important Notes
  • Short Tags: While some configurations of PHP allow for short tags (<? … ?> instead of <?php … ?>), they’re not universally supported and can lead to compatibility issues. It’s best to always use the full <?php ?> tags.
  • PHP Inside HTML Attributes: You can use PHP inside HTML attributes. For example:

<a href=”<?php echo $dynamicLink; ?>”>Click me</a>

  • Always Sanitize User Input: If you’re using PHP to echo or print user input (like form data), always sanitize it to prevent security vulnerabilities like XSS (Cross-Site Scripting).

By following the steps and notes mentioned above, you can seamlessly integrate PHP within your HTML and start building dynamic web pages.

Hurdles Use Php In Html

While using PHP in HTML can provide a multitude of benefits, there are also challenges and hurdles that developers might face. Here are some of the common issues:

Learning Curve: For those who are new to web development or have worked primarily with static sites, the introduction to PHP (or any server-side language) can be a challenge. The transition from understanding how static content is displayed to understanding server-side processing, outputting dynamic content, and handling requests can be daunting.

Setup and Configuration: Unlike plain HTML, which can be run directly in a browser, PHP requires a server environment. Setting up a local server (e.g., using software like XAMPP or WAMP) or configuring a live server might be a hurdle for beginners.

Debugging: Debugging PHP can be more challenging than debugging static HTML. Errors might be due to server-side logic, database issues, or unexpected user input. Identifying and fixing these issues often requires a good understanding of both PHP and the specific server environment.

Security Concerns

SQL Injections: If not properly handled, dynamically generated SQL queries can be prone to injections, which can compromise the database.

Cross-Site Scripting (XSS): Without proper validation and sanitisation, user input echoed back to the page can lead to script injections.

Cross-Site Request Forgery (CSRF): If not protected against, attackers can trick a user into performing an action they didn’t intend to.

Performance: Dynamic content generation can introduce latency, especially if there are complex operations or database queries involved. Proper optimisation and caching mechanisms might be needed.

Inconsistent Environments: Differences in server configurations, PHP versions, and installed extensions between development, staging, and production environments can lead to unexpected behavior.

Maintenance: As sites grow and evolve, the mix of PHP and HTML can become messy, especially if there’s no clear structure or if the PHP code is intermingled with HTML haphazardly.

Templating: While PHP can generate HTML, it’s not primarily a templating language. For larger projects, you might want to use a templating engine (like Twig) or a framework (like Laravel) to keep the presentation layer clean and separated from the business logic.

Deprecated Functions: PHP, like all languages, evolves. Functions that are available in one version might be deprecated in later versions, leading to potential issues when updating or migrating.

Overhead for Small Tasks: For very small tasks or static websites, introducing PHP can be overkill and adds unnecessary complexity

Advantages and Benefits

Dynamic Content Generation: With PHP embedded in HTML, websites can produce content dynamically based on user input, database content, or other variables. For example, display user profiles, list articles, or generate reports.

Interactivity: PHP can process form data, allowing for user interactivity such as user registration, logging in, posting comments, etc.

Database Integration: PHP can interact with databases like MySQL, allowing for data storage, retrieval, and dynamic content presentation based on the data.

Session Management: PHP allows for session management, which helps in keeping track of users as they navigate through the website, enabling features like user authentication.

Reusability and Modularity: PHP allows for the creation of include files. This means you can have a consistent header, footer, or menu file that is included on multiple pages. When you need to make a change, you only have to modify the include file, not every individual page.

Cost-Efficient: PHP is open-source and free to use. This reduces costs for building and maintaining websites.

Vast Community and Resources: PHP has been around for a long time and has a huge community. This results in a vast amount of resources, tutorials, forums, and libraries available for support.

Scalability: PHP is suitable for both small websites and large-scale applications. With the right architecture, PHP applications can be very scalable.

Integration: PHP can be integrated with many other systems and technologies such as CMS, CRM, other APIs, and more.

Points to Consider

Server-Side Execution: PHP is executed on the server-side. This means the client (or user’s browser) only sees the resultant HTML and not the PHP code, ensuring security for your application logic.

Performance: While PHP is generally fast, very heavy computation can slow it down. Proper coding practices, caching mechanisms, and optimised database queries can mitigate this.

Learning Curve: For beginners transitioning from pure HTML/CSS, introducing PHP can have a learning curve. However, its widespread use and extensive documentation can aid the learning process.

Security: While PHP itself is secure, poor coding practices can introduce vulnerabilities. Always be conscious of security best practices, especially when dealing with user input and database interactions.

Final Words

Finally, embedding PHP in HTML is an effective technique to make web pages more interactive, dynamic, and feature-rich. Understanding its strengths and weaknesses, as with any technology, will help you use it efficiently.
