In what scenarios should PHP be used over JavaScript for slider-related functionalities?

PHP should be used over JavaScript for slider-related functionalities when the slider content needs to be dynamically generated or pulled from a database. PHP can handle server-side logic and database interactions more efficiently than JavaScript, making it a better choice for complex sliders that require data manipulation or retrieval. 

<?php
// Connect to database and retrieve slider content
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// Retrieve slider content from database
$sql = "SELECT * FROM slider_content";
$result = $conn->query($sql);

// Display slider content
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo "<div class='slide'>" . $row["content"] . "</div>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
