How can PHP date functions be utilized to accurately display the current month and highlight the current day?

To accurately display the current month and highlight the current day using PHP date functions, you can use the date() function to retrieve the current month and day. Then, you can compare each day with the current day to determine if it should be highlighted.

$currentMonth = date('F');
$currentDay = date('j');

for ($day = 1; $day <= date('t'); $day++) {
    if ($day == $currentDay) {
        echo "<span style='font-weight: bold;'>$day</span> ";
    } else {
        echo "$day ";
    }
}
echo "<br>Current month: $currentMonth";
