Asking me to echo a name back to the screen and it keeps saying it's wrong.
<?php $name = "Mike"; ?> <title><?php $name ?></title>
<?php
$name = "Mike";
?>
<title><?php $name ?></title>

In PHP, we use echo to output a string to the browser like so:
<?php
$name = "Mike";
echo $name;
?>
Hope this helps.

<?php
$name = "Mike";
?>
<title><?php echo $name ?></title>
The only difference is I added the key word echo in front of $name on the last line.

Courses Plus Student 17,967 PointsYou could also write it this way:
<?php
$name = 'Mike';
echo '<title>' . $name . '</title>';
?>

666 PointsI guess I'm confused because I didn't see that in the preceding lesson. Maybe I missed it?
Erin Braxton
666 PointsThanks for your response. So would this need to be included in the opening PHP code every time? The video seems to only show the echo to recall the name or location, etc.?

For example if we wanted to output Hello World to the browser, we would write:
<?php
echo 'Hello World';
?>
The example you provided used a variable called $name to store the string 'Mike' and than used echo to output that string to the browser.

Courses Plus Student 17,967 PointsYou only include echo when you want to output something to the screen. It can be HTML, a string, etc.

666 Pointsokay...thanks. Perhaps I just didn't understand the question but I think I get it.
Erin Braxton
666 PointsThanks, Ted. When the quiz asked me to echo Mike to the screen, I thought I had done that. So maybe I wasn't understanding the working of the question.

The correct code to pass the challenge is:
<?php
$name = "Mike";
echo $name;
Your code:
<?php
$name = "Mike";
?>
<title><?php $name ?></title>
is correct, and would indeed echo Mike's name to the screen. However, Treehouse code challenges are best described as 'picky'. It would be wise to answer questions without adding extra markup :)
