How can PHP be used to retrieve and compare date and time values for conditional rendering of HTML elements?

To retrieve and compare date and time values for conditional rendering of HTML elements in PHP, you can use functions like `date()` to get the current date and time, and `strtotime()` to convert date and time strings into timestamps for comparison. You can then use conditional statements like if-else or switch-case to determine when to display certain HTML elements based on the date and time values. 

$currentDateTime = date('Y-m-d H:i:s');
$targetDateTime = '2022-01-01 00:00:00';

if(strtotime($currentDateTime) < strtotime($targetDateTime)) {
    echo '<div>Countdown to 2022!</div>';
} else {
    echo '<div>Welcome to the new year!</div>';
}
