What's happening is you're trying to log your variable output in line 9 but because you're echoing out as a string, PHP treats it as such and literally outputs $value to the console/screen.

So you're almost there. But try modifying your code so you're referencing the variable name by removing the quotes.

I've also modified the indentation a little bit.

<?php

    foreach ($letters as $value) {
        echo $value;
    };

    echo ".";

Let us know if that helps! :-)

Thanks
