Browsers treat newlines as any other whitespace - so print_r and
var_dump will not, on their own, provide you with a linebreak in a
browser. If you've got xdebug installed, var_dump will provide a nicer
output (including line-breaks).
However, by far the easiest way to check if you're actually getting
linebreaks in your output is checking the source.

If you're suddenly experiencing a change in output, then some of your
environment variables have changed - hard to say which one without
knowing more about your system, but you must obviously have
changed/updated something for this to happen.
