You could write an own function to format the output:
function print_r_html($val) {
echo '<pre>',
htmlspecialchars(print_r($val, true))
, '</pre>';
}
Another option would be to use var_dump(), which gives a nicely
formatted and syntax highlighted output when Xdebug is installed.

Description:
------------
Output of print_r() is often viewed in a web browser, but in this setting, objects are rendered as
long strings that are hard to read, because they have lots of properties, nested objects, etc.
It is much easier to view such output by viewing page source (i.e. actual PHP output), since that
will take into account newlines/whitespace characters that are ignored by (X)HTML browsers.
However, it would be nice to have an optional parameter to make print_r() format its output for a
browser (e.g. maybe <div>'s with inline CSS padding to force indentation, or at least
<br /> and ).
Since print_r() is primarily a debugging tool, this could be pretty handy during development, and
could encourage greater adoption of OOP practices.
ALTERNATIVELY, a tip should be added to the print_r() documentation page telling users that arrays
and objects printed by print_r() can be viewed more easily by looking directly at the source of the
output, rather than through a browser.
Reproduce code:
---------------
N/A, see above.
Expected result:
----------------
N/A, see above.
Actual result:

N/A, see above.
