Why doesn't this work, although it displays correctly in view mode?

<?php

//Place your code below this comment $firstName = "Rasmus"; $lastName = "Lerdorf"; $fullName = $firstName . ' ' . $lastName; echo $fullName .= ' was the original creator of PHP' . "\n"; ?>

index.php
<?php

//Place your code below this comment
$firstName = "Rasmus";
$lastName = "Lerdorf";
$fullName = $firstName . ' ' . $lastName;
echo $fullName .= ' was the original creator of PHP' . "\n";
?>

When you are echoing a concatenated string as you are in the third step you don't need to use the .= operator. You end up reassigning $lastName to be the full string you want to echo by doing that.

<?php
echo $fullName . ' was the original creator of PHP' . "\n";
?>

Or aan even cleaner approach

<?php
echo "{$fullName} was the original creator of PHP\n"; 
// {} are optional but useful in helping to easily see where you're using variables inside of strings.
?>
