ReflectionFunctionAbstract::getDocComment

Beware when you try to use the getDocComment() methods with eAccelerator turned on. eAccelerator »optimizes« your code in a way that it removes any comments from your source. So at runtime you're not able to get any comments and therefor getDocComments return false.

In order to retrieve a comment with this method, the comment must be imediately before the class, function or method, start with /** and end with */
