We can take blend.php (src), and separate the code from the test-cases: utils.php (src), and separately utils-test.php (src). The directive require-once is a run-time instruction which just goes to the require'd file and (effectively) splices it into the current file, and continues evaluating line-by-line. (So it's reminiscent of java's import, but require-once significantly more simple-minded. Beware trampling on identifiers, and it's poor practice to have any dangling tags / code in the require'd file.)
This also lets us separate a program that uses blend from the test cases: some-web-page.php (src), and some-web-page.php (output).
