How can PHP developers efficiently integrate HTML forms within PHP code to capture user input and display dynamic content?

To efficiently integrate HTML forms within PHP code to capture user input and display dynamic content, developers can use the $_POST superglobal to retrieve form data submitted by the user. They can then process this data within their PHP code and generate dynamic content based on the user input. Additionally, developers can use PHP to validate the form data and sanitize it to prevent security vulnerabilities. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Validate and sanitize input data
    $username = htmlspecialchars($username);
    $password = htmlspecialchars($password);
    
    // Process the form data and display dynamic content
    echo "Hello, $username! Your password is $password.";
}
?>

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    Username: <input type="text" name="username"><br>
    Password: <input type="password" name="password"><br>
    <input type="submit" value="Submit">
</form>
