5,117 PointsWhat does echo a name to the screen mean in PHP?
Code challenge question is vague. Don't know if it means to add php code or to include php within HTML for a particular section of code. I need to understand what "to the screen" means within the question, "Now echo Mike's name to the screen."
<?php
$name = "Mike"
<?php echo = "Mike";
?>

<?php
echo $name;
?>
This will output the name Mike to the screen.
Hope that helps!!

Echo is the equivalent in JavaScript of `document.write.... of simply displaying something to the browser page. Which could be a string or a number of any php datatype.
<?php
$name = "Mike"
<?php echo = "Mike";
?>
All this code does, is prints the string Mike, on a web page.

5,117 PointsThanks your Highness:), that helped alot. Some of the questions in the challenges are pretty vague, and some assume more background knowledge than the student has at the time.
