Generator

generator has several distinct usages:

• Yield generator: a function or method that uses yield, implicitly returning an instance of \Generator and implementing the Iterator interface without the boilerplate of writing one
• Random number generator: an algorithm or function, such as rand(), mt_rand(), or the Random\Engine classes, that produces a sequence of numbers that appears random
• Code generator: a tool or library that automates the creation of boilerplate PHP code from templates, configuration, or a schema

Absent further context, generator most often refers to the yield generator.
