<?php function gen() { echo 'start'; yield 'middle'; echo 'end'; } // Initial call does not output anything $gen = gen(); // Call to current() resumes the generator, thus "start" is echo'd. // Then the yield expression is hit and the string "middle" is returned // as the result of current() and then echo'd. echo $gen->current(); // Execution of the generator is resumed again, thus echoing "end" $gen->next();
