Simple version; It's one that's declared unconditionally.
<?php
// Top-level is here
function topLevelFoo() {}
class topLevelBar() {}
if (cond()) {
// No longer top-level
function conditionalFoo() {}
class conditionalBar() {}
}
The longer answer is that it's not just conditionals that can make a
function/class "non-top-level", for example a namespace block makes
its declarations "non-top-level" but I suspect Dmitry will probably
address those in time.
