In your screenshot you're missing the closing curly brace }
for the foreach
loop between lines 9 and 10. It should come right after echo "AB";
<?php
$letters = array("D", "G", "L");
echo "My favorite ";
echo count($letters);
echo " letters are these: ";
foreach($letters as $letter) {
echo "AB";
}
echo ".";
?>
We've set up the loop so that the working variable $letter
will be assigned each of the letters in our $letters
array. We know that the loop will run 3 times and $letter
will get each of the values: "D", "G", and "L" as it loops 3 times. Just because we have that $letter variable, it does not mean that we have to use it. If you look inside the body of the loop, there is only a single statement - echo "AB";
We do not use the $letter variable anywhere inside the loop which is why we don't see any letters from our array. All that happens each time is that we echo "AB" to the page. Since it loops 3 times, we will see "ABABAB".
I think it will make more sense once you complete the remaining tasks.

Courses Plus Student 94,610 PointsI think you're at task 5? Is that an error message you're getting or you're just confused why it's like that?
the foreach loop at that point looks like this:
foreach ($letters as $letter) {
echo "AB";
}
Since $letters has 3 items in it, that loop is going to execute 3 times. At this point in time it will echo "AB" 3 times.
Maybe you can post your code. I'm not sure if you're getting errors or just don't understand why it's doing what it's doing.
