How can PHP be used to dynamically navigate through a gallery of images stored in a MySQL database?

To dynamically navigate through a gallery of images stored in a MySQL database, you can use PHP to query the database for the images and display them one by one based on user input. You can create a simple web interface with navigation buttons to move between images in the gallery. 

<?php
// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "gallery";

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

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

// Query database for images
$sql = "SELECT * FROM images";
$result = $conn->query($sql);

// Display images
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "<img src='" . $row["image_url"] . "' alt='" . $row["image_alt"] . "'>";
    }
} else {
    echo "No images found in the gallery.";
}

$conn->close();
?>
