Subject: [PATCH] Update example to output a single line on PHP 7.2

Somewhere in the development leading up to PHP 7.2, var_dump()
started outputting the file and line number as part of it's output.
This causes one of the end-to-end tests to fail as the example script
it uses outputs twice as many lines as expected.

This fixes this by using var_export() and a little wrapping to output
useful debug data if something goes wrong and sensible output
otherwise.
