Well if you set your error level thingy to E_ALL it'll throw a notice
if you use a variable that you haven't instantiated. But instantiation
basically means 'setting'. So you can do this code:

<?php

$counter = 3;

$countr = $counter + 1; // notice the error (and i only didn't use
$countr++ because that might actually throw the notice)

echo $counter;

?>

and it won't throw a notice as you're using the NEW $countr variable in
a setting sense. However it does help you a little with regards to
CHECKING a variable, e.g.:

<?php

$counter = 3;

echo $countr;

?>

that should throw a notice with errors at E_ALL.

But that's nowhere near a nice Option Explicit.
