What is the equivalent of PHP\'s $this-> in Ruby?
The analog of $this is self, as has been mentioned. However, you asked about $this->, which means you want to use it to access an instance variable ($this->somevar) or instance method (this->somemethod()). For an instance variable, the equivalent in Ruby would be @ (as in @somevar). For instance methods, the equivalent would be to just write the method name (somemethod), or, if you like to be verbose (self.somemethod).
