There was a time when rumors said [] was might be removed for strings, and {} was recommended. Then [] was going to stay and the use of {} is no longer recommended. The manual lists it as an alternative to [] in http://www.php.net/manual/en/language.types.string.php#language.types.string.substr and all examples use the [] syntax.

Confusion was exactly the reason to no longer recommend using {} - because {} is used for the “Complex (curly) syntax” explained in http://www.php.net/manual/en/language.types.string.php#language.types.string.parsing

My 2 cents on this.
