Position 1 might be a good way of saying first character of a string though,
since it isn't a completely numerical thing being dealt with.
substr("abcd",1,1) being "a", instead of substr("abcd",0,0), just looks more
correct in this context to me.
Why isn't there a strlen() in the documentation?  :-)
