Modern PHP

Generators

Generators are similar to iterators that calculate their values on demand, thus potentially using fewer resources. They can be created using the yield keyword, e.g.:

function my_generator()
{
  yield 1;
  yield 2;
  yield 3;
}

Generators are forward-only iterators, i.e. you can only request the next value, not the previous, next but one etc. They are useful for iterating sequential data sets such as reading a file line by line (in order).

Built-in web server

PHP comes with a built-in web server which is useful for development purposes, although it should never be used in production.

• Configuration directives: -c config/php.ini

Useful dependencies

• FastRoute
