How can one display the current week in a calendar using PHP?

To display the current week in a calendar using PHP, you can use the `date` function to get the current week number and then loop through the days of the week to display them in a calendar format.

<?php
// Get the current week number
$week_number = date('W');

// Loop through the days of the week and display them
for ($i = 0; $i < 7; $i++) {
    $day = date('Y-m-d', strtotime("this week +$i days"));
    echo $day . "<br>";
}
?>
