I’ve got some code that is cobbled together from a couple of different places & it’s got namespace collisions that wouldn’t exist if I’d been starting from scratch. But I’ve got what I’ve got … and, occasionally, new code falls over because a class has already been declared.

Luckily, there’s a way to find out from where a class was loaded:

			$strClassName = "Oracle_Cred";
			if( class_exists($strClassName) ){
				$reflector = new \ReflectionClass($strClassName);
				echo "Class $strClassName was loaded from " . $reflector->getFileName();
			}
			else{
				echo "Class $strClassName does not exist yet";
			}
