echo php variable between php scripts

I was given a script with different variables that are based on date and time on the top of XHTML Strict page.

<?php
date_default_timezone_set('America/Los_Angeles');
$time = new DateTime();
if($time < new DateTime('2011-10-31 18:00')){
    $title="Before Halloween";
    $cb1="2011,10,31,18,0";
}else if
    ...
?>

Halfway through the HTML code I have a second PHP script:

<?php
dat开发者_运维知识库e_default_timezone_set('America/Los_Angeles');
countdown(2011,10,31,18,0);
function countdown($year, $month, $day, $hour, $minute)
{
    ...
?>

How can I echo $cb1 from the upper script into the second script so the third line looks something like countdown(echo $cb1); and updates automatically based on the upper script?

Since it is a string you will need to explode (take apart) at the comma, to create 5 variables. To do this you would use:

 $cbarray = explode(",",$cb1);
 countdown($cbarray[0],$cbarray[1],$cbarray[2],$cbarray[3],$cbarray[4]);

Or something simalar by putting each one in a named variable.

You could try to set $cb1 as a session variable instead so you can access it from anywhere in the file.

Maybe replace:

$cb1="2011,10,31,18,0";

with

$_SESSION['cb1']="2011,10,31,18,0";

And then your code in the second script would be: countdown($_SESSION['cb1']);
