How can the date on a web server be adjusted in PHP?

To adjust the date on a web server in PHP, you can use the `date_default_timezone_set()` function to set the desired timezone. This function allows you to specify the timezone that you want to use for date and time functions in your PHP script.

// Set the timezone to your desired location
date_default_timezone_set("America/New_York");

// Now you can use date() function to get the current date and time in the specified timezone
echo "Current date and time: " . date("Y-m-d H:i:s");
