How can PHP be utilized to dynamically set and adjust time-based restrictions on website content?

To dynamically set and adjust time-based restrictions on website content using PHP, you can utilize the date and time functions in PHP to check the current time against predefined restrictions. By comparing the current time with start and end times of the restrictions, you can control the visibility of content on your website.

$current_time = time();
$start_time = strtotime("2022-01-01 00:00:00");
$end_time = strtotime("2022-01-31 23:59:59");

if ($current_time >= $start_time && $current_time <= $end_time) {
    // Display restricted content
    echo "This content is only visible between January 1st and January 31st, 2022.";
} else {
    // Display alternative content or hide content
    echo "Content is not available at this time.";
}
