What are some potential pitfalls of using PHP to dynamically change images on a website based on the season?

One potential pitfall of using PHP to dynamically change images on a website based on the season is that the code may not account for caching mechanisms, leading to outdated images being displayed. To solve this issue, you can add cache busting to the image URLs by appending a query string with a timestamp or version number. 

<?php
// Define an array of seasonal images
$seasonalImages = [
    'spring' => 'spring-image.jpg',
    'summer' => 'summer-image.jpg',
    'fall' => 'fall-image.jpg',
    'winter' => 'winter-image.jpg'
];

// Get the current season based on the month
$currentMonth = date('n');
$season = '';

if ($currentMonth >= 3 && $currentMonth <= 5) {
    $season = 'spring';
} elseif ($currentMonth >= 6 && $currentMonth <= 8) {
    $season = 'summer';
} elseif ($currentMonth >= 9 && $currentMonth <= 11) {
    $season = 'fall';
} else {
    $season = 'winter';
}

// Generate a cache-busting query string
$cacheBuster = time();

// Output the image tag with the seasonal image
echo '<img src="' . $seasonalImages[$season] . '?v=' . $cacheBuster . '" alt="Seasonal Image">';
?>
