1) Add the start of a foreach loop with an opening curly brace between the third and fourth echo commands. The foreach loop should load each element from the letters array, one at a time, into a working variable named letter. (2) Add the closing curly bra

Ah OK, so what they want you to use is a foreach loop.

foreach($arrayString as $newArrayString) {
    echo $newArrayString;
}

$arrayString is the value of the string array. In this case, it would be $letters.

$newArrayString is what the $arrayString is renamed too, in this case $letter.

The foreach loop will echo each array value one at a time and will start with the code right after the {, then stop at the } and go back to the { until all arrays have been echoed.

If you are not completely understanding this, they go over how to use a foreach loop in great detail a video or two before the coding quiz :)

The fourth echo statement, the one inside the foreach loop, should display my favorite letters from the array INSTEAD of AB. Remove the static piece of text from that fourth echo statement, changing it instead to display the value for the array element under consideration inside the foreach loop.

$letters = array("D","G","L"); echo "My favorite "; echo "3"; echo " letters are these: "; foreach($letters as $letter){ echo $letter[D]; echo $letter[G]; echo $letter[L]; echo "AB"; } echo ".";

it didnt work.

You have to close your curly brace after echo"AB"
