Can't figure out Step 2

Can someone explain how they solved this? The last two video were confusing to me.

Step 2 asks you to echo out each flavor, so you'd do this:

foreach ($flavors as $flavor) {
  echo $flavor;
}

And for step 3, you need to only echo out the flavors that are in stock, which you need to check with a conditional statement such as a ternary:

foreach ($flavors as $flavor) {
  echo $flavor["in_stock"] ? $flavor : "";
}

Or a regular if statement:

foreach ($flavors as $flavor) {
  if ($flavor["in_stock"]) {
    echo $flavor;
  }
}

Notice that we don't need to check if ($flavor["in_stock"] === true) because the value is already a boolean, hence why we can just do if ($flavor["in_stock"]).

I hope this helps! :-)

Thanks for the thorough explanation! It helped a lot. However, to display only the "name" key of each $flavor, I found that

echo $flavor["name"];

allowed me to do so.
