Can someone help with string concatenation?

I've tried a few different ways but can't seem to get it right. For example...


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

You need to add echo at the end.

echo "$fullName was the original creator of PHP." . "\n";

Hi, James Ackerman, everything fine?

To concatenate one string in PHP, we have several methods. I'll show you some of them:

$string = "String can have some $variables directly, but you will need always doublequote"; $string = "We can also ".$concatenate." some strings this way."; $string = sprintf('Or even, we could %s and insert our values', 'use a function to let things more clear');

Remember that as pointed before, you will always need to echo your string, otherwise, it will be just inside your code!

@David That got it. I thought I had tried it with echo, but apparently I used echo with an incorrect submission. I ended up assuming I was adding something that wasn't being called for. Thanks much!

@Pedro Thanks for the additional information!
