PHP Include/Require limit?

Question

I use the pretty large Library PHP Image Workshop (http://phpimageworkshop.com/) at my project. It is about 75,5 KB. Everything works fine but if I try to include a 15 KB file with country codes, it fails. With the other files I easily get over 100 KB inclusion size, so my question; Is there a size limitation for include?

Answer 1

Afaik - only in case if your PHP process instance exeeds allowed memory limit. Other then this - explain how does it fail exactly. Any error messages? Errorous behavior?
