ReflectionClass::__clone
Running the following code on Windows Vista (I know, I know), PHP 5.3.9, the ReflectionClass constructor actually throws a ReflectionException when the desired class cannot be instantiated:
<?php
try {
$ReflectedClass = new ReflectionClass('NonExist');
} catch (LogicException $Exception) {
die('Not gonna make it in here...');
} catch (ReflectionException $Exception) {
die('Your class does not exist!');
}
?>
ReflectionClass::__construct

Useful to know that if you pass a string into the construct and the class cannot be instantiated for some reason a SPL LogicException will be thrown.
This code was ran on a Mac OS X 10.6.7, AMP, PHP 5.3+
<?php
// index.php
try {
$ReflectedClass = new ReflectionClass('NonExist');
} catch (LogicException $logicDuh) {
print_r($logicDuh);
}
?>
Will return a deeply nested array full of useful information about the error.

It's very useful to know that you can also use the ReflectionClass to inspect interfaces, even thouth Interfaces are not classes. Example:
<?php
interface Edible
{
public function eat();
}
$refl = new ReflectionClass("Edible");
$methods = $refl->getMethods();
?>
