PHP 5.5 Generator

function fibonacci(){ $a = 0; $b = 1; while(true) { $a = $a + $b; $b = $a - $b; yield $a; } }

$fib = fibonacci(); $fib->current(); $fib->next(); $fib->current();

$fib is now a generator object.

So we can generate number now, and the local variable in the function keep it current state.

Alternative, an old solution pre php 5.5 way of doing this is for loop.
