the trend towards an increased usage of Ruby on Rails. Statistics aside,
Ruby on Rails has some advantages over PHP, which are discussed below.
1. Ruby on Rails is more object-oriented than PHP, thus providing all
the inherent advantages of an object-oriented language such as
simplicity, modularity, modifiability, extensibility, maintainability
and re-usability.
2. Ruby on Rails is web framework whereas PHP is only a scripting
language.
