php concatenation is removing php output?

I have a php variable that is created like so:
$scholarshipTitleOutput = ($scholarship['field_sec1_title']['#items'][0]['value']);
If I print the variable by itself it renders correctly, but I want the output to be placed between two header tags. What I would expect to be able to do it echo out the following...
echo "<h2>" . $scholarshipTitleOutput . "</h2>";
But this removes the variable output from the page for some reason. I've tested further and found that I can concatenate after echoing the variable to do things like add a space...
echo $scholarshipTitleOutput . " ";
So what is it about that first example that is completely removing the variable from outputting on the page?
解决方案
It works fine when I try it. You can also try
echo "<h2>{$scholarshipTitleOutput}</h2>";
