Can I count on the print_r function to output info in the same format
always?
I did a print_r on an array and got something like this:
Array
(
[status] => 0
[email] => bob(at)coolgroups(dot)com
[firstname] => bob
[lastname] => smith
[id] => 148
[access] => 2040ad981d3302d63564b990fea38268
)
I want to make sure that doesn't change in PHP 6 or 7.

No, if you want a consistently formatted text representation of an array
to, for example, transfer data between applications, you might be better
either using the json encoding, or the built in serialisation, or writing
your own array to text function.
Obviously, whichever one you use, you'll need matching routines at the
the other end. json encoding is fairly well supported with code or
libraries available for many different languages at www.json.org
Although there's nothing there for ada, fortran or pascal yet :(

I wouldn't count on that. You probably have a better chance with
var_dump() which (apart from being more accurate) is used in unit
testing in the PHP code itself. E.g.:
http://svn.php.net/viewvc/php/php-src/trunk/tests/func/010.phpt?view=markup
I mean, they can change it whenever they want, but they'll break their
own tests.
(I hope you're are planning to write unit tests or something like that;
there are betters choices to store or transmit information.)
