What are some alternative approaches to displaying images in PHP based on user input, aside from the method described in the forum thread?

The issue is that the current method described in the forum thread only displays images based on static file paths, and does not take into account user input or dynamic image sources. One alternative approach to displaying images based on user input is to store the image file paths in a database and retrieve them based on user input. 

// Assuming you have a database table named 'images' with columns 'id' and 'file_path'

// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Retrieve image file path based on user input
$user_input = $_GET['user_input']; // Assuming user input is passed through GET parameter
$sql = "SELECT file_path FROM images WHERE id = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param("i", $user_input);
$stmt->execute();
$stmt->bind_result($file_path);
$stmt->fetch();

// Display image
echo '<img src="' . $file_path . '" alt="image">';
