I just went back to the challenge and it's basically asking exactly what you have for your second example.

<?php
      // The first half asked you to create a variable set to the String "Mike"
      $name = "Mike";
      // The second half just asked to echo "Mike" to the screen using the variable.
       echo $name;
?>

Also, always pay attention to your semi-colons.

It looks the same to me. I don't know where I did wrong

You were missing a semi-colon above, right after the word "Mike". Just copy and paste the formatted example in it will pass. I just tried it twice.

Yep~ It works. Maybe I should not put a space after 'Mike". Thank U!

Sorry I did not notice sooner Kaeley, Treehouse notified me, but I was out as it's saturday lol... You can have a space after "mike", and the semi-colon does not even have to come on the same line for PHP (not sure about the test criteria); but you do need a semi-colon separating statements in PHP, and it is considered best practice to put them clearly visible on the same line as the statement ends, because it makes it easier to check for their absence.

so 

    <?php // open PHP
    $name = "Mike"; // notice both quotes are double quotes
    $name = 'Mike'; // This is not needed, but also valid, as both quotes are single quotes, it's about the quotes being the same
    echo $name; // put $name in the output stream, which in a webpage comes out on the page as text
    // you do not need to include any close tag unless you have non-PHP after the PHP ?>

Hope this adds a little to your understnding of David's answer and PHP in general :D
