1,805 PointsCan't figure out Step 2
Can someone explain how they solved this? The last two video were confusing to me.

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! :-)

1,805 PointsThanks 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.
