PHP Include Files

PHP Include Files is a feature that allows developers to include external PHP files in their code. This can be useful for organizing code, reusing code across multiple pages or applications, and separating functionality into different files. Here’s an example of how to use PHP include files:

  1. Create a file called “header.php” with the following content:
<!DOCTYPE html>
<html>
<head>
    <title>My Website</title>
</head>
<body>
    <header>
        <nav>
            <ul>
                <li><a href="#">Home</a></li>
                <li><a href="#">About</a></li>
                <li><a href="#">Contact</a></li>
            </ul>
        </nav>
    </header>
  1. Create a file called “footer.php” with the following content:
    <footer>
        <p>© My Website 2022</p>
    </footer>
</body>
</html>
  1. Create a file called “index.php” with the following content:
<?php
    include 'header.php';
?>
    <main>
        <h1>Welcome to My Website</h1>
        <p>This is the home page of my website.</p>
    </main>
<?php
    include 'footer.php';
?>
  1. Save all three files to the same directory on your server.
  2. When you visit the “index.php” file in your web browser, you will see the header and footer sections from the “header.php” and “footer.php” files, respectively, along with the main content from the “index.php” file.

By using PHP include files, you can separate your code into smaller, more manageable files that can be reused across multiple pages or applications. This can help to make your code more organized, easier to read, and easier to maintain over time.
