ReflectionClass
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!');
}
?>

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();
?>

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.
