But then, if you think about it, it makes perfect sense. Think about it: what is an array: an enumeration of various data types. What is a string: an enumeration of characters. So, since they are both enumerations, it makes sense to be able to access strings as arrays. Also, they are not going to remove the curly brace syntax. If my memory is good, they said using curly braces when accessing string elements instead of square brackets is faster for the simple fact that:
- square brackets are made for array data types, and:
- curly braces were later optimized for string data types (in php 4.x I believe)
