I think you may have got a tad off course for the task. Task 1 just wants you to modify the for each loop so that it also grabs the ISBN as well as the title. I'm not sure why you have a GET in there with a Hard-Coded index?
All you need for the first task is a simple addition to the loop to also grab the ISBN using the => symbol. Below is the corrected code for Task 1. I hope it will make sense now.
<?php
$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";
$books["978-0192840509"] = "Aesop's Fables";
$books["978-0520227040"] = "Mahabharta";
$books["978-0393320978"] = "Beowulf";
