How can web pages be accessed through a web server using PHP?

Web pages can be accessed through a web server using PHP by creating PHP files that contain the HTML code for the web page content. These PHP files are then uploaded to the web server, where they can be accessed by users through their web browsers. The web server processes the PHP code and serves the resulting HTML content to the user's browser.

<?php
// This is a basic PHP file that can be accessed through a web server
// It contains HTML code for a simple web page

// Start the PHP script
echo "<!DOCTYPE html>";
echo "<html>";
echo "<head>";
echo "<title>My Web Page</title>";
echo "</head>";
echo "<body>";
echo "<h1>Welcome to my web page!</h1>";
echo "<p>This is some example content.</p>";
echo "</body>";
echo "</html>";
?>
