header("Content-type: foo/bar") tells the browser what kind of file you
are serving. After that, you have to output the contents of the file.

imagepng outputs the image as a PNG.

Outputting a text file would go like this:
<?php
header("Content-type: text/plain");
echo "Hello world";
?>

Using echo $x; instead of header($x); would work in your example.
