Functions and methods names are not case-sensitive. But variables names are case-sensitive. — Rohan Patil, Oct 05 '12 at 09:08

See below url:-

Are PHP functions case sensitive?

http://www.wellho.net/mouth/93_Case-Sensitive-.html

Read it

I am quoting from this:

Note: Function names are case-insensitive, though it is usually good form to call functions as they appear in their declaration.

So, its looks like user-defined is case-sensitive, there were a vote for making functions/objects under PHP5 case-sensitive.
