I have 2 PHP documents; my main index.php and my data.php which gets some info from a database and puts it into variables. How would I echo some variables from the data.php in the index.php?

Suppose below is your index.php file:
<?php
// This is index.php
// Your initial code .....
require 'data.php'; // in data.php set some variables, arrays etc.
// Now you can print the variables, arrays from data.php file in index.php
?>
Let me know if this does not make sense.

Thanks thats exactly what I wanted
If you want really different files. You have to save your data in a session or in your database.
Or otherway if you redirect from one to another send your data over GET or POST.

You can use the global keyword in front of the variable you want to use, in the file you wish to use it to tell your files that something should be available in all your files, so long as the file is being included.

In the index.php
$variable = 'value';//Initialize before including
require_once "data.php";
In the data.php
echo $variable;
A better approach is having a file containing all variable initializations which are needed in all the files in the script execution and then requiring this file before the files which are going to use the variables

A better solution is to make function that obtain data in data.php, and include this file to index.php with executing this function, f.e.:
file data.php:
<?php
function getData()
{
return 'data';
}
file index.php:
<?php
require_once 'data.php';
$data = getData();
echo $data;

you can use include() ,require_once() or require() for include data.php in index.php file.
sessionorget/postthe data from one page to another
