gettype

  • Variables in Ruby don’t have a type. Instead they are an instance of an object. We can interrogate the class of an object instance using Object#class.

    PHP

    print gettype(true);         // => boolean
print gettype(1);            // => integer
print gettype(1.2);          // => double
print gettype('hello');      // => string
print gettype(new stdClass); // => object
print gettype(null);         // => NULL

    Ruby

    true.class       # => TrueClass
1.class          # => Fixnum
1.2.class        # => Float
"hello".class    # String
Object.new.class # Object
nil.class        # NilClass
