In other words, it will halt the script whereas include only emits a warning (E_WARNING) which allows the script to continue.

Remember, when using require that it is a statement, not a function. It's not necessary to write:
require('somefile.php');
?>

The following:
require 'somefile.php';
?>

Is preferred, it will prevent your peers from giving you a hard time and a trivial conversation about what require really is.

If your included file returns a value, you can get it as a result from require(), i.e.

foo.php:
return "foo";
?>

$bar = require("foo.php");
echo $bar; // equals to "foo"

When using an include file to define one or more global variables (to avoid having to redefine them in multiple files), make sure you're referencing the same variable. 

[global.php]
   $app_dir = "/app/path/here";

[main.php]
include "global.php";
