What is the correct syntax for using PHP's date function in JavaScript code?

When trying to use PHP's date function in JavaScript code, you need to remember that PHP is a server-side language while JavaScript is a client-side language. To use PHP's date function in JavaScript, you can output the desired date format using PHP and then pass it to your JavaScript code as a variable. This way, you can utilize PHP's date function to generate the date format you need and then use it in your JavaScript code.

<?php
$date = date('Y-m-d H:i:s');
echo "<script>var currentDate = '$date';</script>";
?>
