What are some best practices for creating and managing PHP scripts that generate images for each day in a countdown?

When creating PHP scripts that generate images for each day in a countdown, it's important to organize your code efficiently to avoid redundancy and make it easy to manage. One way to do this is by using a loop to dynamically generate images for each day in the countdown. Additionally, consider using a template system to easily update the design of the images if needed.

<?php
// Set the end date for the countdown
$end_date = strtotime('2023-01-01');
$current_date = time();

// Calculate the number of days left in the countdown
$days_left = ceil(($end_date - $current_date) / (60 * 60 * 24));

// Loop through each day in the countdown and generate an image
for ($i = 1; $i <= $days_left; $i++) {
    // Generate image using GD library or any other image manipulation library
    // Save the image with a unique filename for each day
    $image_filename = "day_" . $i . ".png";
    // Save the image to a directory
    imagepng($image, "images/" . $image_filename);
}
?>
