I have written a script to print the following:

There are -4290 days (including today) until Christmas.

There are -4322 days (including today) until my birhtday.

The code is below:

Complete the functions required.

<?php

    function compute_days($date){
        
    }

    function print_days($days, $event){

    }

    // declares the variable $days and assigns it to the result of the compute_days function,
    // which has been sent the value of Christmas day.

    $days = compute_days('12/25/2011');


    // Sends the result of the previous function (held in the variable $day) and the event name to the print_days function to print to screen.

    print_days($days, 'Christmas');

    // overwrites the variable $days and again assigns it the result of the compute_days function,
    // which this time has been sent the value of my next birthday.

    $days = compute_days('11/23/2011');


    // Sends the result of the previous function (held in the variable $day) and the event name to the print_days function to print to screen.

     print_days($days, 'my birhtday');

?>
