Is the PHP ReflectionClass a singleton?

Question

I have a need to get the ReflectionClass instance of a class from a few different places in my code. I was going to manage a singleton instance of it myself for performance reasons. However, I thought PHP may already do this.

If you new up a ReflectionClass for the same class multiple times, does PHP manage the singleton for you or do any other kind of caching?

Answer 1

No, reflectionClass is not a singleton; nor does it have any intelligence "built in" to act as a singleton if you try to instantiate multiple reflectionClass instances for the same class/object. Each instance of reflectionClass is totally autonomous
